Question

Why are metals generally good conductors of electricity? 1. metals have more protons. 2. metals have strong bonding with other atoms. 3. metals have free electrons in their outer shell?

Answer 1

Metals are good conductors of electricity because of the free electrons that is present in their outer shell that makes them good conductors of electricity. This is the most accepted fact that for any thing to transmit electricity by being a good conductor they need more free electrons in their outer shell

Answer 2

metal have free electrons in their outer shell which make them generally good conductors of electricity. Example is the copper which is used for electrical wiring since is a good conductor of electricity. copper with electronic configuration of (Ar)4s2 has two free electrons in their outer most shell which allow it to conduct electricity.
