Ions with more than one possible oxidation state should be named with a
roman numeral as above. The old system of nomenclature gives the lesser
charge an ˆous ending and the higher charge an-ic ending. In the sets of
three, the old naming system applies to only the two lowest charges. (Cr2+
, Cr3+)
