Rating Newest Oldest. Best Answer: Metals are good conductors because they have unfilled space in the valence energy band. Also,metals are soft, has a low melting point and happens to be reactive taht's why they can easily conduct heat/electricity easily.
This allows electrons to move freely carrying an electrical charge. Because of this, metals are commonly used to make wires and other devices to carry electrical current. On the other hand, metals are not perfect conductors. Impurities in metals cause electrical resistance by keeping the electrons from moving smoothly. Increases in temperature likewise slow down the flow of electrons by causing electrical resistance. Wires that are thinner or longer also provide more resistance to electricity than thicker or shorter wires.
