==Key Stage 4==
===Meaning===
An [[Ion]] is a [[particle]] that has a different number of [[proton]]s to [[electron]]s.
===About Ions===
: An [[atom]] contains the same number of [[proton]]s as [[electron]]s. When an [[atom]] loses or gains [[electron]]s it becomes an [[ion]].
: [[Ion]]s can be [[Positive Charge|positively charged]] or [[Negative Charge|negatively charged]].
: If an [[atom]] gains [[electron]]s it becomes a [[Negative Charge|negatively charged]] [[ion]] since there are more [[electron]]s than [[proton]]s and [[electron]]s carry a [[Negative Charge|negative charge]].
: If an [[atom]] loses [[electron]]s it becomes a [[Positive Charge|positively charged]] [[ion]] since there are more [[proton]]s than [[electron]]s and [[proton]]s carry a [[Positive Charge|positive charge]].
