It is safe to assume that all other metals given to you for naming purposes will be polyvalent (form more than one charge), and do require a roman numeral in the names of their compounds. You are also expected to know the charges formed by the non-metals. A. Romero 2008 IA IIA IIIA IVA VA VIA VIIA VIIIA Representative Elements Rep. Elements
