The Formation of Ionic Compounds

44

• Ionic compounds: composed of ions, charged particles formed  when an atom (group of atoms) gains or loses electron(s).

• Ionic compounds typically form when a metal reacts with a  nonmetal.

• Each metal atom loses a small number of its electrons and  becomes a cation, a positively charged ion.

• The nonmetal atoms gain the electrons lost by the metal atoms  and become anions, negatively charged ions.
