QUESTION

# What is the ionic compound name for fe2o3?

It is: Iron (III) Oxide

As a transition metal iron can have two oxidation states Fe^+2 ferrous or Fe^+3 ferric.

Oxygen has an oxidation state of O^-2.

In the case of Fe_2O_3 the oxidation states are balanced when 2 Fe^(+3) ions pair with 3 O^-2.

Fe_2O_3 is Iron (III) oxide where the roman numeral informs us that the charge on the iron is +3, the common name would be ferric oxide.

If the iron was Fe^(+2) and the oxygen O^-2, the formula would be FeO Iron (II) oxide or ferrous oxide.
