periodic table color coded fo group names

The left-most column is called group one. The vertical columns in the periodic table are called groups or families (depending on whom you ask). Vertical columns in the periodic table are called groups (or families). The fifth period elements have one 5s, three 5p, and five 5d orbitals available.

These are the electrons located in the last shell or energy level of an atom. The elements of the second row of the periodic table-which is cleverly called the second period-have one 1s and three 1p orbitals available for their valence electrons. The elements of the first row of the periodic table (the single, isolated squares in the upper-left and upper-right corners) have a 1s orbital available for their electrons to sit in-all comfy and cozy.

These orbitals (s, p, d, and f) are the area around an atom where its electrons are most likely to be found. Every element in the same period has the same number of atomic orbitals. Even though some boxes appear to be missing, all of the rows go left to right, skipping over any blank areas. Horizontal rows of the periodic table are called periods. 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. Periodic Table Guide The Hitchhiker's Guide to the Periodic Table
