[[File:Stainless-etched-kettle.jpg|thumb|Stainless kettle]][[Iron]] and other metals are chemically ''reactive''. Upon exposure to air, a metal surface will react with the oxygen, which results in the formation of a thin metal oxide film. This occurs completely spontaneously. The metal oxide film makes the surface more ''passive'' (resistant) to other chemicals in the environment. This is called "passivation" by a chemistry definition.<ref name=a967/><ref name=Crookes>Crookes R.
