Why is copper used for making electric wires?
I believe an atom of copper is missing one electron in it’s valence shell (the outer shell of electons spinning around the nucleus)so that makes it very easy for electrons, under the influence of a voltage, to sort of skip accross the surface of a copper wire, the electrons continue to be transferred from one copper atom to the next, this transfer becomes harder as the copper heats up and the atoms reach a higher state of excitement and begin to vibrate faster, its kind of like trying to hit a moving target
