1. Identify the cation: The symbol Mg corresponds to magnesium, a group 2 metal with a fixed +2 charge.
2. Identify the anion: The symbol Cl corresponds to chloride, the anion of chlorine.
3. For ionic compounds with fixed-charge metals, name the cation first, then the anion. No prefix is needed for the anion, as the charge of the metal determines the number of anions required.
