You already know that the Cr has a 2+ charge, the sulfate ion has a -2 charge. you write the two ions with the charge and swap the charge of one has a sub-index of the other and vice versa without the charge symbol\[Cr ^{2+}SO _{4}^{2-}\] \[Cr _{2}(SO _{4})_{2}\] then you simplify to keep the smallest number possible \[CrSO _{4}\]
