Metals conduct electricity because:

Answer: Valence electrons are delocalized and free to move through the lattice The delocalized "sea" of valence electrons can flow when a potential is applied, giving metals their conductivity.

Metals conduct electricity well because

Answer: They have a 'sea' of delocalized valence electrons that move freely Metallic bonding: cation lattice in a sea of mobile electrons. Explains conductivity, malleability, and metallic luster.
