The oxidation states of iron, however, differ. Atoms of iron do not form the + 8 oxidation state corresponding to the loss of all the electrons in the 3d and 4s orbitals. This is in contrast to the adjacent element manganese that can lose all its 3d and 4s electrons to form the + 7 oxidation state.
Oxidation of iron was studied in oxygen and in steam at 650–750 °C. Linear-parabolic kinetics were observed on oxidation of iron in steam. Steam significantly improved the scale adhesion. Pt mark indicated inward transport of oxidants in steam. Abstract

Iron oxide is an important biological agent that has a key role in medical processes; however, the mechanism whereby it provides iron for human and animal cells and its biological uses remains unclear. We aimed to evaluate the effects of oral iron oxide on serum iron status and compare the results with those of iron sulfate as a reference salt.
There are sixteen iron oxides and oxyhydroxides (often collectively referred to as "iron oxides") (Cornell and Schwertmann 2003 ). Most iron oxides contain iron in the trivalent state (Fe (III)); only three oxides – wüstite (FeO), magnetite (Fe 3 O 4 ), and Fe (OH) 2 contain iron in the divalent state (Fe (II)).
So far the majority of experimental work has focused on the most stable iron (hydr)oxides (like hematite and goethite). Maghemite (γ-Fe 2 O 3) is rare investigated ferric oxide (Garcell et al. 1998) though is …
