"WebSince the overall charge is 0, the positive and negative charges from the irons and oxygens have to sum up to 0. The least common multiple between 2 and 3 is 6 so we have to multiply the +3 by 2 to get +6, and the -2 by 3 to -6. This means we need 2 iron atom, and 3 oxygen atoms, or Fe2O3. Hope that helps. 2 comments. " - Ionic charge of selenium
