Aluminum oxide consists of atoms of aluminum and oxygen bonded together. ... structure changes just enough to become chemically inert and thus unable to react rapidly with additional water molecules or atmospheric oxygen. This change in molecular structure is why aluminum oxide metal resists corrosion.
