Has a full valence shell (8ve-) positive + area surround the nucleus no charge, 0 protons + neutrons electrons farthest from the nucleus, responsible for reactivity/bonding negative - sad atom, doesn't have a full valence shell (less then 8) so it wants to bond with others center of an atom, contains protons and neutrons
