Answer: FeO is called ferrous oxide while Fe2O3 is ferric oxide
Explanation:
Ferrous oxide, commonly known as iron(II) oxide contains iron that lost 2 elections in the oxidation process. So it is able to bond with other atoms that have an extra 2 electrons to share. Ferric oxide, is commonly known as iron(III) oxide
They are lost from valence shell (it's outermost shell of an atom).
