Two negative charges from the two chloride ions.....

Explanation:

Salts are electrically neutral. In magnesium chloride or calcium chloride or ferrous chloride, the charge on the metal centre is equally balanced by the chlorides. $C {l}^{-}$ bears a single negative charge, and thus 2 equiv of chloride are required to give a salt.
