Presentation Transcript
More than one possible charge? • 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. • 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
