In chemistry, the adjective Ferrous indicates a compound that contains iron(II), meaning iron in its +2 oxidation state, possibly as the divalent cation Fe . It is opposed to "ferric" or iron(III), meaning iron in its +3 oxidation state, such as the trivalent cation Fe . This usage has been largely replaced by the IUPAC nomenclature, which calls for the oxidation state being indicated by Roman nu

Iron (II) oxide is an chemical compound composed of iron in the +2 oxidation state bonded to oxygen atoms. It easily converts to a mixture of iron and iron (III) oxide at room temperature. It is stable though when it is very hot. It is a black powder. If it gets hydrated (bonded to extra water molecules), it turns green.
