: [[Element]]s above [[Hydrogen]] but below [[Carbon]] are found in [[mineral]]s, which are [[metal]] [[compound]]s, so they need to be [[Extraction of Metals|extracted]] by using [[Carbon]] to [[Displacement Reaction|displace]] the [[metal]] from the [[compound]].
: [[Element]]s above [[Carbon]] are found in [[mineral]]s but they cannot be [[Extraction of Metals|extracted]] with [[Carbon]] because [[Carbon]] is less [[Reactivity|reactive]] than those [[metal]]s so we use [[electrolysis]] to [[Extraction of Metals|extract]] them.
==Key Stage 4==
===Meaning===
The [[Reactivity Series]] is a list of [[metal]] [[element]]s in order of how easily they can lose [[electron]]s to form [[Positive Ion|positive ions]].
===About The Reactivity Series===
: The [[reactivity]] of a [[metal]] is determined by how easily it can lose [[electron]]s to form [[Positive Ion|positive ions]]. When [[metal]]s are placed in order of their [[reactivity]] it is called the [[Reactivity Series]].
: The more easily a [[metal]] can lose [[electron]]s to become a [[Metal Ion|metal ion]] the more [[reactivity|reactive]] that [[metal]] is.
: The [[Reactivity Series]] can be found [[experiment]]ally by [[observe|observing]] the [[Chemical Reaction|reaction]]s between [[metal]]s and either [[water]] or [[acid]].
: [[Metal]] [[element]]s which can lose [[electron]]s more easily than [[Hydrogen]] is able to lose its [[electron]] will react with [[water]] and with [[acid]]s.
: The [[Rate of Reaction|rate of reaction]] and the [[energy]] released during a [[Chemical Reaction|reaction]] is directly related to the [[metal]]'s [[reactivity]]. The faster the [[Chemical Reaction|reaction]] and the more [[energy]] released during that [[Chemical Reaction|reaction]] the greater the [[reactivity]] of that [[metal]] [[element]].
