Full Answer

Metals are typically good conductors because of their ability to donate electrons. Most metal atoms have one or two valence electrons, which means that they want to give these away in order to become more stable. When electrons are introduced, they are quickly passed through the chain of metal atoms.

The opposite of conductors are insulators, which either prevent or heavily limit the flow of electrons. These are typically made out of non-metal materials like glass.
