Question

How do you name transition metals with roman numerals?

Answer 1

Examples : `MnO, FeCl_2, CuSO_4, Pb(NO_3)_2, Fe_2O_3`

Explanation:

Mn (II) Oxide = "Manganese two oxide"

Iron (II) Chloride = "Iron two chloride"

Copper (II) Sulfate = "copper two sulfate"

Pb (II) Nitrate = "Lead two Nitrate"

Fe (III) Oxide = "Iron three oxide"

Whenever you have a transitional metal, make sure you don't forget to add those Roman numerals, because transitional metals often have many oxidation numbers and by putting the number in parenthesis we can distinguish which oxidation number we are dealing with.
