Chloride ions have a charge of 1-. Since the charge on an Mg ion is 2+, the formula unit of Magnesium Chloride is MgCl2. There are 2 chloride ions for each Mg ion.
The chemical formula for calcium chloride is CaCl2 - Ca++ ionically bonded with 2 Cl-.
Pbcl2
the chemical formula of lead chloride is PbCl2
2, that's why the number 2 is after the Cl in the formula.
