Changes

: [[Magnesium]] is a more [[Reactivity|reactive]] [[Alkali Earth Metal|alkali earth metal]] than [[Beryllium]] but less [[Reactivity|reactive]] than [[Calcium]].: [[Magnesium]] is more [[Reactivity|reactive]] than [[Carbon]] on the [[Reactivity Series|reactivity series]] so it must be [[Extraction of Metals|extracted]] from its [[ore]] using [[electrolysis]].

: [[Magnesium]] [[Chemical Reaction|reacts]] slowly with [[liquid]] [[water]] and strongly with [[steam]] to produce [[Hydrogen]] [[gas]] and [[Magnesium Hydroxide]] and strongly with [[acid]] to produce a [[Magnesium]] [[salt]]s.

: [[Magnesium]] is a [[solid]] at [[STP|standard temperature and pressure]].
