==Key Stage 3==
===Meaning===
'''Free electrons''' are [[electron]]s which can move from one [[atom]] to another.
===About Free Electrons===
: [[Electron]]s are normally bound to a single [[atom]]. '''Free electrons''' are able to move from one [[atom]] to the next.
: [[Material]]s with '''free electrons''' can have an [[Electrical Current|electrical current]] when a [[Potential Difference|potential difference]] is applied.
==Key Stage 4==
===Meaning===
'''Delocalised electrons''' are [[electron]]s which can move from one [[atom]] to another.
===About Free Delocalised ===
: [[Electron]]s are normally bound to a single [[atom]]. '''Delocalised electrons''' are able to move from one [[atom]] to the next.
: [[Material]]s with '''delocalised electrons''' can have an [[Electrical Current|electrical current]] when a [[Potential Difference|potential difference]] is applied.
: A [[Metallic Bond|metallic bond]] is held together by the '''delocalised electrons''' which are attracted to the [[Positive Charge|positive]] [[Metal Ion|metal ions]].
