Elements in the Periodic Table are arranged in periods (rows) and groups (columns). Atomic number increases as you move across a row or period. The period number of an element signifies the highest unexcited energy level for an electron in that element. Elements within a group share several common properties. Groups are elements have the same outer electron arrangement. The outer electrons are called valence electrons.
