Non-metal elements have a COMMON or fixed charge/oxidation when compounded with metals.

3 Since these metals can form multiplecharges they will compound with nonmetals (or polyatomic ions) in differing ratios. Therefore, the Roman numeral designation is required inthe nomenclature to specify the correct compound. For example, there are several types of manganese oxides, each with characteristic chemicaland physical properties. Manganese (III) oxide, Mn2O3, is a black mineral insoluble in water. Whereas, manganese (VII) oxide, Mn2O7, is adark reddish mineral which is soluble in water. Manganese will also form two other oxides each with differing colors and 2005 by Matthew Medeiros.
