One atom of iron (Fe) with charge of 2+ and 2 Cl atoms with charge 1- each. This is so because chlorine will always have a charge of 1-, and the roman numeral in the parenthesis tells you that the charge of the iron is at 2+. It is positive because it is a transition metal. Here, it would tell you if the molecule had a charge, therefore it is neutral, therefore the charge of Fe should match the charge of Cl. Therefore, the compound is FeCl2.
