The periodic table of elements is a table that organizes the elements found in nature according to increasing atomic numbers (the atomic number is determined by how many protons are in the atomic nucleus of an element). It is an extremely useful way in which to classify, systematize and compare all the various forms of chemical behavior. Credited most often with being invented by Russian chemist Dmitri Mendeleev, the table has wide application to the fields of physics, engineering and biology. Now you or your favorite chemistry student can have a quick reference to the table while doing your homework on the computer! This mousepad features a listing of the table with symbol elements, and their atomic numbers and weights. Colorfully categorized into different groups, this is sure a lot better than the old-school bland mousepad! A fun way to make even a Monday morning at the office a little more interesting!
