Report Abuse. Metals are good conductors of electricity because the electrons are free to move in a network of metal atom. So because of the Sea of Electrons, these electrons do not belong to just one atom but move freely about the metal's network which makes them great conductors of heat and electricity.etals are good conductors of electricity because the electrons are free to move in a network of metal atom.
