The Periodic Table of elements has a lot of information in a relatively small place. At a glance we can tell the atomic symbol of the element; its Atomic Mass; and the number of protons, neutrons, and electrons it has. Upon further examination, we can note such periodic trends as electronegativity (tendency of the element to attract electrons), atomic radius (the distance between the nuclei of two bonded atoms), and ionization energy (how much energy it takes to remove electrons from an atom. We can also tell the ionic charge of a number of the elements.

Basically, the periodic table is easy access to a lot of information crucial to science.
