    CrCl3 The chromium atom has a +3 charge and chloride has a -1 charge so to balance out the charge you need 3 chloride ions.

    Aluminum Sulfate - This is all you need since there is only 1 ion for aluminum and for SO4 so any person can figure out the formula using this name.

    SO4^2- is sufate, a polyatomic ion. Al is 3+ and it is never any other charge.
