Transition Metals

More than one possible charge? Ionic compounds that have transition metals COULD need Roman Numerals in the name. Ionic compounds that have transition metals COULD need Roman Numerals in the name. If the transition metal has MORE THAN ONE possible charge, then it requires a Roman Numeral in the name. If the transition metal has MORE THAN ONE possible charge, then it requires a Roman Numeral in the name. The Roman Numeral IS the charge on the transition metal. The Roman Numeral IS the charge on the transition metal.

Roman numerals 1 – I 2 – II 3 – III 4 – IV 5 – V 6 – VI 7 – VII 8 - VIII
