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. H.Periodic Table Guide The Hitchhiker's Guide to the Periodic Table.(But do pay attention to their terms of service!)
