The atoms of copper contain electrons and the atoms of rubber also contain electrons. Then why does copper conduct electricity but rubber does not conduct electricity?

The main property shared by conductors is that the atoms that make up the material have some loose electrons on the outside (called conduction bands); where the electrons can move from one atom to the next. Electrical current is the movement of electrons in a conductor. If a material lacks these free electrons (also called conducting electrons)as rubber doesit will not conduct electricity and is called an insulator.
