The metallic structure

Metallic structure showing positive metal ions, delocalised electrons, electrical charge flow, and thermal energy transfer

A metal is a giant lattice of positive metal ions surrounded by a sea of delocalised electrons. Each metal atom releases its outer-shell electrons, which become shared across the whole structure.
