How to write a formula with transition metals • When a Transition metal is involved in the bond, you must identify which form of the atom is bonding. • These atoms can have different oxidation numbers. • Look for the Roman Numeral in the name when writing the formula. The Roman numeral is the oxidation number of the transition metal. Copper (II) Fluoride Cu+2 2 F -1 Cu. F 2
