The only difference here is that we have to specify the charge of the transition metal ion by using a Roman numeral, and keep in mind that a transition metal is an element with an atomic number of 21 to 30, 39 to 48 or 57 to 80. Roman numeral ChargeI +1II +2III +3IV +4V +5VI +6 The reason we do this is not for the sake of nostalgia for bygone Roman numerals nor to imitate movie credits. Because transition metals can assume more than one charge, we have to specify which one is involvedExample: manganese(II) oxide contains Mn+2 and O-2. So we just need one of each and the formula becomes MnO. Copper(I) oxide is Cu2O. To go backwards, we need to figure out the charge of the transition metal. Example: What is the correct name of CrCl3 ? The charge of Cr is unknown = x . But chloride = (-1). The sum of the charges has top be zero, so: x +3(-1) = 0. x = 3.Answer: CrCl3 = chromium (III) chloride.© 2004 Cavalcade Publishing, All Rights Reserved For chemistry help, visit
