Metal Oxides have an oxidation nuer of -2 and generally comprise of an oxygen anion. The Earth’s crust is mostly made up of oxides that are solid. Oxide coatings can get formed over pure elements too, for instance, a foil made of aluminium gets covered by a thin skin of Al 2 O 3 , and this skin defends the rest of the foil from corrosion .

Oxides | AMERICAN ELEMENTS

Oxides. Oxides are compounds that contain one or more oxygen atoms and one or more other atoms. Oxide compounds make up a large proportion of the earth’s crust – nearly all metals naturally occur as minerals in oxide and compound forms which require processing and treatment to obtain the pure metal. The electronegativity of oxygen allows it
