In a metal like copper some of the electrons are not bound to individual atoms. If a voltage is applied across a copper wire these free electrons flow from one atom to the next. This flow of electrons is an electric current but the copper atoms themselves do not move so the copper wire does not vanish. Of course, the voltage source must ...

How many total valence electrons are in copper?

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.
