A cation is a type of ion that has a positive electric charge.[1] This means it has fewer electrons than protons. The opposite of a cation is an anion, which has a negative charge.
Cations can have only one atom (monatomic cations) or be made of multiple atoms together (polyatomic cations). Most metals form monatomic cations, while polyatomic cations are rarer.
