An electron that is not attached to one particular atom and can move through the whole metallic structure.
Revise: Metallic Bonding MechanismModels therefore often represent a metal as a regular array of positive metal ions surrounded by delocalised electrons. The complete piece of metal is still electrically neutral: the total positive charge is balanced by the total negative charge.
