The elements in the Periodic Table are arranged in order of increasing atomic number because it represents the number of protons in the atomic nucleus. It is the number of these protons, and their corresponding number of electrons, that determines the chemical properties of each element.

It was found that when the elements lined up, the groups vertically had similar properties. They also increased by atomic mass. The table displays the patterns created by elements of similar properties.
