An ion is a positively or negatively charged atom (or group of atoms). An ion is formed by the loss or gain of electrons by an atom, so it contains an unequal number of electrons and protons. Example: Sodium ion Na+, magnesium ion Mg2+, chloride ion Cl–, and oxide ion O2–. There are two types of ions : cations.
