An electron that is not attached to one particular atom and can move throughout a structure.
Revise: Types of Chemical BondsThe delocalised electrons are shared throughout the structure, rather than as pairs between particular atoms. They are sometimes described as a ‘sea of electrons’. The strong electrostatic attraction between these negative electrons and the positive metal ions is metallic bonding.
