For example, consider binary ionic compounds of iron and chlorine. Iron typically exhibits a charge of either 2+ or 3+ (see [link] ), and the two corresponding compound formulas are FeCl 2 and FeCl 3. 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.
