The shiny grey magnesium strip changes to a white powder called magnesium oxide. Learn more about making a reactivity series in this guide. For example, sodium is burned to make sodium oxide.

its freshly exposed shiny surface rapidly turns dull as a thin layer of sodium oxide forms: Other metals may oxidise more slowly. Gold and other very unreactive metals do not oxidise in air at all.
