iron oxide, commonly known as rust, forms as iron corrodes in an oxygen environment. iron is especially eager to bond with oxygen, which is why pure iron is rare on the earth's surface. corrosion requires the presence of an anode that gives up electrons, a cathode that accepts electrons, and an electrolyte that facilitates the flow of electrons between them.read more≫
