AP Chemistry Periodic Table - What is It?

AP Chemistry Periodic Table - What is It?A good AP Chemistry periodic table PDF is a must for every student, teacher and parent of any child with AP Chemistry in the future. I have made a couple of notes about this since there has been some news about a study going on regarding the composition of the periodic table and the chemicals therein.I will only say that I believe the overall composition of the AP periodic table and chemical is not a concern of any sort. Chemicals with names and terms have been used for years in the history of science. They are not kept so very closely to the tables and charts of physics as we are led to believe. These chemical names actually refer to substances and are not used in chemistry on a regular basis, although many find them very interesting and may have a chemistry related hobby or interest.However, when we refer to a periodic table or chart of periodic elements and compounds, this is the first word to go with it. In fact, a good AP Chemistry period ic table PDF will help you identify the letters of each element as they come on a sheet of paper.Many years ago, when the AP periodic table was first created, they did not include oxygen. The reason was because no one thought to add one, until some people added oxygen to the table, and then we all knew what that symbol meant. The chemical formula in this case is shown on a sheet of paper by writing in their full name and then how they interact with each other.When the first edition of the free periodic table of the elements was published by H. Herschel, no one realized that the elements would be included and there would be an oxygen, hydrogen and nitrogen on the first table.By the way, there is a periodic table of free radicals and then a periodic table of oxygen. As far as I am concerned, the periodic table of periodic elements and compounds only includes those three elements.So if you are looking for AP Chemistry periodic table PDFs, you can get one from the World Wide Web. There are lots of sites with these files, but I believe that the ones that do have the greatest diversity are the ones that were developed by the manufacturers of chemical laboratory equipment. It is interesting to see how these websites react to criticism.

Tips for Introverts on How to Be More Emotionally Healthy at Work - Introvert Whisperer

Introvert Whisperer / Tips for Introverts on How to Be More Emotionally Healthy at Work - Introvert Whisperer Tips for Introverts on How to Be More Emotionally Healthy at Work Emotional health is all about feeling happy, fulfilled, and confident at work. It takes into account your duties, the people you work with, and your standing within your company. While each person has their own vision of emotional health, for introverts, emotional health involves different needs and coping tools than their extroverted counterparts. If you’re looking to be more emotionally healthy in your workplace, there are a few things you can do to increase your happiness. Be Transparent About Your Needs There are a lot of things about the average office that can negatively impact an introvert’s emotional health. A distracting open office setting, bosses who are combative, and meetings with no warning can be irritating and frustrating for someone who isn’t introverted, but someone who is introverted may have their emotional health impacted greatly by these things. If there’s something in your office that’s affecting you, be transparent with your boss about what’s negatively impacting you and how you would like it to change. Afterward, if you can pinpoint some changes in your work life that indicate you’re in an emotionally healthy place, you know those changes are making a big difference in your happiness. Don’t Be Afraid to Take a Mental Health Day If you’re struggling with your mental and emotional health, it’s good to allow yourself to take mental health days in order to recharge. Taking a sick day allows your body to recover by resting and relaxing, while also not infecting anyone at work â€" and the same applies to your mental health. Allow your mind to rest and relax while not taking any frustrations out on your colleagues or your duties. Introverts should take a mental health day any time they are feeling overwhelmed at work so that they don’t drive themselves to depression or anxiety, which is something some introverts experience. Take an impromptu day off, or plan it out in advance. Either way, it can help with your work-life balance. Be on the Lookout for Burnout Burnout is not specific to introverts. In fact, it’s a big issue in small businesses that often need all hands on deck, which is why many small business owners, employees, and individuals work to be aware of burnout symptoms and treat their employees as valuable resources. Those symptoms include anxiety, depression, anger, insomnia, and illness. These symptoms can be the same for introverts, but there are often more causes. Burnout can be caused by working long hours, taking limited breaks, and taking on stressful projects. For introverts, burnout can also be caused by too much collaboration, excessive meetings, stressful client interactions, and management stresses as well. If you’re an introvert, you might experience burnout even if you’re not overworked, so be on the lookout for symptoms so you can work on your self-care. Take Breaks During the Workday Sometimes it’s not about coping with emotional health issues, it’s about maintaining good emotional health. Fortunately, breaks can do both. For introverts, breaks aren’t just about recharging your brain to complete more work. It’s also about recharging your mental health in order to spend more time with colleagues, managers, and clients. Taking a mental health day can do that, but so can taking small breaks in each workday to be alone and in a quiet place. This is one way to set a realistic limit that can work to improve your work-life balance. Find a quiet bench outside, take a walk around your building, or put your headphones in and go to a quiet breakroom a few times a day and allow yourself to recharge. Find Stress Relief Tactics that Work for You It can feel like stress is just a normal part of life at work. However, stress can cause big problems for your emotional health. One myth about stress at work is that it affects everyone in the same way. That is not true, and neither are the stress-relief tactics you can use. One person may react to stress by getting angry, but an introvert might react to stress by disconnecting and shutting down. One person might vent to a friend as a way to relieve stress, but an introvert might need time alone to cope. Help your emotional health at work by finding a tactic that can help when you feel stressed. Try a few things until you find something that works, like breathing techniques or going to the gym, instead of drowning in the stress. Good emotional health is a vital part of feeling happy at work. No one wants to go to a job every day that leaves them feeling overwhelmed, burnt out, stressed, and unhappy. For introverts, it’s as much about being misunderstood is it is about being overworked. This is why it’s important to take a look at your working situation and check in with yourself. Just like physical health, good mental health is all about being mindful and taking care of yourself.

ChaptersThe Life of Euclid the MathematicianEuclid's Seminal Text  ElementsWhat is Euclidean Division?Euclid's Mathematical AxiomsWhat You Should Know About the Greatest Common DivisorOver the centuries, the history of mathematics has witnessed the rise of many greats: Pythagoras, Thales, Newton, Archimedes. Here, we will be discussing the infamous Euclid. A great mathematician from antiquity, Euclid managed to revolutionize all of the established body of knowledge of his era in one sole work: Elements. In this way, Euclid forms the basis of mathematics as we learn it today.Trigonometry, algebraic reasoning, equation, fraction, logarithm â€" all of these aspects of math are still marked by the mathematicians of antiquity.Euclid’s axiom, Euclidean division, Euclidean geometry, Euclid’s algorithm - keep reading to find out about the history of math throughout its various scientific discoveries.

Only some written texts dating many years after Euclid’s death have been found, and it is only from these that we have managed to capture historical fragments of the career of the now famous mathematician, Euclid.There is no other mathematician from antiquity that is more celebrated Euclid. Born in Athens around 330 BCE, Euclid’s studies w ere formed in the beautiful Egyptian city of Alexandria, then under the reign of king Ptolemy I. There, Euclid frequented the notorious Museum of Alexandria, the hub of intellectual life in the city.Unlike his predecessors, Euclid did not create his own school for mathematics. However, the scientist certainly had many students and disciples that formed his own personal entourage, to whom he passed down all of his knowledge and wisdom. This entourage also took part in developing many of his experiments.One legend has it that Euclid had given an insignificant amount of change to one of his students while he had asked him what Euclid was getting out of his mathematical research. In other words, Euclid was not in search of money. Instead of big fortunes, the mathematician preferred to nourish his brain with mathematical formulas and numbers of all types.Euclidean thought inspired antiquity and contemporary philosophers alikeEuclid is known most for his work entitled Elements that was wr itten around 300 BCE. Both a success in his times and in today’s world, this work was the second most printed book, after the bible, at time of the invention of the printer of the 15th century.Elements, divided into thirteen books, is dedicated essentially to plane geometry and arithmetic. Triangles, parallel lines, circles â€" Euclid proved many theorems in his book (including the Pythagoras theorem), introduced notions of GCD (greatest common divisor) and introduced repeated, successive subtractions which are now known as Euclidean divisions. These could be seen as the predecessor to what Isaac Newton would later create: calculus!Euclid’s knowledge was based on knowledge that had long been acquired from the greatest mathematicians of antiquity.In this epoque, sciences were making their way around Greece and influenced a great number of budding scientists. Euclid and his contemporaries’ discoveries continued to inspire the sciences a long time after his death, estimated at ar ound 265 BCE in Alexandria.For more famous mathematicians from antiquity, check out the great Archimedes!Euclid's Seminal Text  ElementsEven though he wrote some other influential works, Elements is considered to be Euclid’s main work. A great scientific success, the mathematician catalogues in this work all of the proofs of geometric knowledge that were ever known until then.The first six books in Elements deal with the geometric plane. Here, we find information about triangles, parallel lines, the Pythagorean theorem, planes, the properties of a circle (in the presence of figures in a circle), the construction of the Pentagon and the proportions between its sizes.These first books are widely recognized as one of the first moments in which the basics of geometry are detailed with the characteristics of figures and their applications. This later formed the basis of the creation of analytic geometry by Rene Descartes!The three books that follow don’t deal with geometry but with a rithmetic. In this section, Euclid discusses prime numbers, the construction of the GCD of two or more integers, numbers in geometric progression, and the construction of perfect numbers. This first section of chapters in Elements is also known for its introduction of a repeated, successive subtraction process now called Euclidean division.Fragments left over from the original publication of ElementsThe second book is dedicated to irrational quantities. It is comprised of the three last books, which are devoted to geometry in space. Here, we see the construction of objects like the sphere, regular solids, the pyramid, the cube, the octahedron, the dodecahedron, the icosahedron, etc.Other books have been grafted onto Elements during the course of its centuries long. These were written by new mathematicians that wanted to develop and add onto the chapters therein.All of the books of the body of work Elements form the basis of the curriculum of mathematics that are taught today. The ge ometric plane, geometry in space, arithmetic â€" these all form part of the mathematical courses given from primary school to higher education, which is the reason why Elements is considered the Bible for mathematics.The seminal work was long considered as the reference material for the mathematical world before being re-discussed centuries later. All of the information given by Elements can be seen as a photograph of the representation of the physical world in Euclid’s time.

It is nothing more than the division that one learns in elementary school.Also called whole division, it is composed of an operation between two whole numbers called a dividend and a divisor, which gives the results called the quotient and the remainder.Making a Euclidean division of one number A (the dividend) by one number B (the divisor), permits us to try to find a whole quotient. That is to say, the whole integer found at the end of the division is called the remainder, which is the part of the dividend that we cannot divide further.To better understand, here’s an example:With the dividend of 25, we divide by 4 (the divisor). The quotient turns out to be 6 because 6 X 4 =24. What is left over is 1. The number 1, then, is the remainder.The common way to write this type of division is to place the dividend on the left side and the divisor on the right. The remainder is found under the dividend while the quotient is found under the divisor.To verify that you have finished the operation, make sure that the remainder cannot be divided further. It will be necessarily smaller than the divisor. It could be that the remainder is zero. In this case, we say that A is a multiple of B.Euclidean division is an integral part of our elementary courses, although this division can and does get more complicated with the addition of decimals, etc.Euclid includes in his works an explanation on conic sectionsEuclid's Mathematical AxiomsIn his work Elements Euclid wrote many axioms, which are mathematical propositions that are held as evident. It was at this moment in history that the mathematical world decided to designate name “axiom” to all mathematical rules that were at once elementa ry and logical.Euclid gave 5 in his work:“A straight  line segment can be drawn joining any two points.“Any straight  line segment can be extended indefinitely in a straight  line.“Given any straight  line segment, a  circle can be drawn having the segment as  radius  and one endpoint as center.“All  right angles are  congruent.What You Should Know About the Greatest Common DivisorThe Euclidean algorithm is also an important concept taught in mathematics courses and deals with the highest common factor. Also called the greatest common denominator, the GCD is the biggest common divisor between two integers. Just like Euclidean division, it is also considered to be a part of simple arithmetic.To find the GCD, it is necessary to make a list of all the divisors that two numbers possess. For example, take 10 and 26:10: 1,2,5,1026: 1,2,4,9,13In this case, the greatest common divisor would be the number 2.In order to avoid having to make a list of all the possible divisors for each number, the Euclidean algorithm consists of making a series of Euclidean divisions. Applying this concept, it suffices to simply divide the biggest number by the smallest one and proceed to divide until the remainder is equal to 0.The Euclidean algorithm is explained in book seven of Elements. Euclid first presents his research in the form of a geometric problem. He then searches to find the unit of measure for two segments. To do this, he decides to subtract the smallest segment by the biggest and to continue until he finds the ideal measure. This method is now the base of all division and the cause of many headaches in primary school!Check for maths tutors with proven record of achievements here.

The Only Way to Boost Your GMAT Verbal Score

The Only Way to Boost Your GMAT Verbal Score GMAT MBA Admissions Blog Simply put, the only want to boost your GMAT verbal score is to read more (of basically anything, including novels), read more intentionally and actively, and then practice lots of GMAT reading comprehension, sentence correction, and critical reasoning questions. Of course, there are some specific strategies to employ for each of the GMAT verbal question types, but simply engaging in more reading is most of the battle. Students who start out with very low levels of confidence with math, i.e., students who “aren’t math people,” tend to be particularly stressed and frustrated with standardized tests like the GMAT. But paradoxically, improving your quantitative skills is in many ways much easier than your verbal or reading comprehension skills. Here’s how John Easter, senior MyGuru GMAT tutor and founder of Jedi Prep, puts it â€" “Reading and comprehending are as fundamental as it gets. Math is a skill that you acquired through education. Someone taught you to count, add, subtract, multiply, divide, and solve quadratic equations by ‘completing the square.’ Verbal skills, on the other hand, just appeared out of thin air between 12 and 18 months after you were born. Of course, you had to learn to read, but that can and does happen incredibly fast. Soon after you learn basic phonics you can “sound-out” new words and build your vocabulary without any assistance. By the time you were 4, you probably knew about 5,000 words, at 8 around 10,000 words, and now you probably know 20,000 to 35,000 words. In all probability you were reading books with extended, complex plots and multiple characters at the same time you were struggling to learn a 12 by 12 multiplication table. Think about that for a while, and if you’re not amazed think about it some more. We can teach you how to solve quadratic equations by “completing the square” if you’ve forgotten most of the algebra you learned in high school. We can teach you any math that you once learned and have now forgotten. We can even teach you a lot of math that you never learned in the first place. Unfortunately, we cannot re-teach you how to read and comprehend.” So if it’s particularly difficult to improve reading comprehension skills, what can a student preparing for the GMAT and struggling to improve their GMAT verbal scores do? Well, in our new (free) eBook The 7 Rules for Improving Academic Performance, rule #5 is simply to read more (i.e., books, magazines, newspaper, anything, really), and to do so intentionally. To read intentionally, or to read actively (vs. passively) simply means to go slow, ensure you understand everything you’re reading, and to stop and ask yourself questions like: What was the main point/theme/argument I just read about… …and how would I summarize it in 1-2 sentences? What logic was used to piece the narrative together? What facts/evidence were employed to support the key assertions? When you do this, you will slowly build skills related to comprehending complex arguments, making logical connections, and employing complex English grammar and vocabulary. Building these skills will boost your GMAT verbal score in the long run, without question. At MyGuru, we’d argue that literally any type of reading, done consistently over time, will improve your performance on verbal, reading comprehension, or English portions of standardized tests. However Magoosh offers a specific recommendation, tailored to what is tested on the GMAT, in their “Complete Guide to the GMAT” eBook. “Not surprisingly, one of the best ways to prepare for GMAT Reading Comprehension is simply to read…one of the best sources of reading as you prepare for business school is a weekly news magazine called The Economist. The Economist is one of the most intelligent weekly journals in print, and it brings a highly sophisticated perspective to all issues affecting micro- and macroeconomics. Its articles explore economics, politics, demographics, technology, etc. It targets the highly intelligent. If you can understand tone and implication in Economist articles, you will have absolutely no problem with these tasks on GMAT Reading Comprehension…if you make a habit of reading it, that will give you an edge in business school, and after that, and edge in the business world.” When it comes to improving your GMAT verbal score, as it relates to reading comprehension specifically, John puts it like this â€" “Improving your RC skills takes time, persistence, and focused practice, focused practice, focused practice! Did I mention focused practice? In our next blog article, we’ll review John’s specific “recipe” for improving your GMAT-reading comprehension score through focused practice. hbspt.cta._relativeUrls=true;hbspt.cta.load(215486, 'ec7de4d5-7dbc-47df-88fd-67e762d72f81', {});

The only thing is that GoPuff won’t force you to be healthy you have to muster up your own willpower not to order five bags of Doritos. If you can force yourself to make good choices about what you order, GoPuff is the way to go because of the sheer amount of options that you have at your fingertips. GoPuff is available in most major U.S. cities. 3. UberEATS UberEATS is Uber’s fairly new food delivery service that has been rolling out in cities across America over the past few months. It’s extremely accessible and efficient all you need is an Uber account, which many college students already have. Since Uber is already a popular service among college students, the brand recognition is sure to keep Uber benefiting from that demographic. Again, like GoPuff, UberEATS isn’t inherently healthy; the healthy options are there, you just have to make them. No one else is going to make them for you. What UberEATS can do is make those healthy options more accessible. 4. Grocery Store Delivery This option is less known as it is just starting to gain traction. If you are in need of some healthy groceries, but can’t find the time to go on a grocery trip, check with your local grocery stores about delivery options. Many health-oriented grocery stores, like bfresh, offer grocery delivery options. You make a list and someone shops and delivers all of the food requested to you. It’s a great option for if the grocery store is far away or hard to get to with a busy schedule. Not all grocery stores offer a delivery service, but it’s definitely worth researching options that your local stores may offer. pexels.com This list is in no way exhaustive. There are so many local food delivery organizations in every city that offer their own unique take on the service. Make sure to check out your local food delivery companies for any money-saving deals they may offer. The beauty of food delivery services is that healthy foods are so much more accessible now because of them. Health-oriented restaurants and grocery stores are much less common than pizza and burger joints, which means they are more difficult to get to. Unless you’re lucky, healthy places are often far away from where you live and just aren’t worth the time it takes to get there. Food delivery services eliminate the logistical difficulties that may be involved with physically getting yourself to a healthy restaurant. Calculating up the cost of transportation, the cost of food delivery could even end up being less than if you were to travel to these restaurants on your own. When it comes down to it, healthy eating is more of a choice than anything else. There are companies like the ones listed that will hand deliver healthy food to you, but you still have to make the choice to order that healthy food and then actually eat it instead of dining hall mozz sticks. It might be tough sometimes, but with so many delivery options, there really is no excuse. Anything can be a healthy food delivery service if you want it to be you just have to take the right steps!
