Metals are good conductors of electricity because the valence electrons in metallic crystals are free to move.

Explanation:

Metallic bonds joins atoms of metals and alloys together. The formation of this bond type is favoured by large atomic radius, low ionization energy and a large number of electrons in the valence shell.

The metallic bond is responsible for the bulk of the physical properties of metals we know such as malleablility, ductility, electrical and thermal conductivity e. t. c.
