... How do we write oxidation numbers for transition elements? The oxidation number of a transition element can be determined by TWO methods. 1. The Roman numeral (stock system) indicating the charge (oxidation number). Ex: iron (II) is Fe+2 iron (III) is Fe+3 2. The suffix ending (old system): Ex: fer ...
