| + | Rust is the common name for iron oxide. An oxide is a chemical compound containing an oxygen atom and other elements. Oxides are formed when elements come into contact with air, through a process known as oxidation. Oxides are common, forming most of the earth's crust. When iron (or steel, which contains mostly iron) is exposed to air, it combines with the oxygen in the air, and forms iron oxide -- rust. | ||
