In this method

Step 1: we will take Magnesium to form compound with sulphate.

Step 2: First we should know the component of compound that are magnesium and sulphur. Step 3: Now we have to write the valency of both components that is of magnesium 2 as it is bivalent and of sulphur is 2 as it belongs to halogen family.
