	Iron(II) oxide - Wikipedia, the free encyclopedia
		Iron(II) oxide, also known as ferrous oxide or ferrous iron, is one of the iron oxides.
		Iron(II) oxide is an example of a non-stoichiometric compound and the ratio of the elements iron and oxygen can vary due to crystallographic vacancies.
		Iron(II) oxide should not be confused with rust, which usually consists of iron(III) oxide (ferric oxide).
