WebIn this post, I will explain why metals are such good electrical conductors, and also explain how nonmetals like water and glass can also become conductors. Metals conduct electricity because they have “free electrons.”. Unlike most other forms of matter, metallic bonding is unique because the electrons are not bound to a particular atom.
