Old system of naming Instead of using roman numerals use suffix "ous" for the lowest oxidation number and "ic" for the higher.Instead of using roman numerals use suffix "ous" for the lowest oxidation number and "ic" for the higher. Ex: Copper I would be Cuperous and Copper II would be Cuperic.Ex: Copper I would be Cuperous and Copper II would be Cuperic.
