![]() ![]() So there was a method to Mendeleev's madness. Within the grid, there are rows and columns that help organize elements with similar properties together. This creates patterns in the table called periodicity (more on that later). ![]() The elements are placed in specific locations on the periodic table grid according to the way they look and act. This information is very useful when solving all kinds of chemistry problems on exams and quizzes. As the name suggests, this is the mass of a single atom of the element. One final piece of information found in the elemental box of most periodic tables is the atomic weight. In case you're curious, Hg is derived from the Latin word "hydrargyrum," which means "liquid silver." Very fitting if you ask us. Mercury's chemical symbol, for example, is Hg. For other elements, the symbols are not as obvious. For many an element, the symbol is just the first two letters of its name, such as Co for cobalt. These symbols are simple two-letter abbreviations of the elements' names. Clever, is it not?Īll periodic tables also contain the chemical symbols for each element. ![]() ![]() For cobalt, the atomic number is 27 because all cobalt atoms have 27 protons. This value, unique to each element, indicates the number of protons present in the nucleus of an atom. One piece of information found in every periodic table is the atomic number (located in the upper-right corner in the example above). Cobalt, you say? It wouldn't have been our first choice, but if you insist. Let's take a closer look at an individual periodic table box. If the bells and whistles of a fancy table don't appeal to you, stick to a more basic table like this one here. Some contain more information, some less. Each element has its own cheat sheet of chemical information found in a specific place within the grid.ĭon't be worried if the periodic table you're used to doesn't look exactly like the one above. You may have noticed the periodic table looks like a big rectangular-ish grid. The periodic table is the tool chemists have concocted to organize all of the elements, which are substances (like carbon or hydrogen) that cannot decompose into simpler substances. Who hasn't spent time organizing their Skittles to accurately reflect the rainbow? Chemists are no different than the rest of us. In fact, we might say it's elementary, my dear Watson. Have you ever wondered why the table is the way that it is? What was good ol' Dmitri thinking when he put certain elements in one row and other elements in a different one? At first it may seem like a random mess of numbers and letters, but there is, indeed, a method to the madness. Check out the colors, the rows, the columns, and the symbols. Take a good, long look at the periodic table, Mendeleev's favorite creation. The basics of organic nomenclature, of inorganic nomenclature and polymer nomenclature are also summarized in a collection of Brief Guides.Periodic Table Guide The Hitchhiker's Guide to the Periodic Table It is a valuable introduction to all other color books, Red, Blue, and Purple. Like the first edition of 1998, it is directed towards teachers and students of chemistry in schools and universities, but it should be equally useful to people such as government officials concerned with customs and taxation who need some acquaintance with chemical names, but generally have little knowledge of chemistry. This edition of Principles of Chemical Nomenclature was edited by G.J. Principles of Chemical Nomenclature: A Guide to IUPAC Recommendations, 2011 RSC Silver Book: Compendium of Terminology and Nomenclature of Properties Clinical Laboratory Sciences Purple Book: Compendium of Polymer Terminology and Nomenclature Red Book: Nomenclature of Inorganic Chemistryīlue Book: Nomenclature of Organic Chemistry Green Book: Quantities, Units and Symbols in Physical Chemistry The IUPAC Color Books are the world’s authoritative resource for chemical nomenclature, terminology, and symbols. Terminology definitions published by IUPAC are drafted by international committees of experts in the appropriate chemistry sub-disciplines, and ratified by IUPAC’s Interdivisional Committee on Terminology, Nomenclature and Symbols (ICTNS). ![]()
