The Periodic Table orders elements by its number of protons. The 1st element has 1 proton, the 2nd has 2, and so on. Furthermore, elements with similar characteristics are grouped vertically. These elements(1A-8A) have the same number of electrons in their outer shell, so react similary. Elements organized horizontally have progressively more protons and electrons.
