Free electrons are electrons which can move from one atom to another.

Electrons are normally bound to a single atom. Free electrons are able to move from one atom to the next.

Materials with free electrons can have an electrical current when a potential difference is applied.

Delocalised electrons are electrons which can move from one atom to another.

Electrons are normally bound to a single atom. Delocalised electrons are able to move from one atom to the next.

Materials with delocalised electrons can have an electrical current when a potential difference is applied.

A metallic bond is held together by the delocalised electrons which are attracted to the positive metal ions.
