Cation Name: Iron (II) Cation Charge: 2+ Anion Name: Nitrate Anion Charge: 1-

Work Step by Step

Since Iron has more than one ionic charge, we will start with the anion. The anion is NO$^{-}_{3}$. It has a 1- charge. But since there are two nitrate ions in the compound, there is 2- charge from the negatively charged ions. In order for the compound to have a net neutral charge, the iron atom must have a 2+ charge, making it Iron (II).
