How do metals conduct electricity?
Metallic bonding forms a closely packed lattice structure of positive ions with delocalized electrons (these are the electrons of the outer shell of the metal atom).
Because these electrons are delocalised, they can move freely within the metal structure when an electrical current is applied.
