Is metal a good conductor or an insulator?

Explanation:
Metals conduct electricity well because their atoms release outer electrons to form a sea of freely moving electrons. These delocalized electrons can drift when a voltage is applied, allowing charge to flow with relatively low resistance. The same mobility also makes metals good at transferring heat. Insulators bind electrons tightly, blocking flow, while semiconductors conduct less unless conditions like temperature or doping boost their conductivity. So, metal is a conductor.
