Why are materials such as glass and rubber good insulators? R = Because in these materials there are no free electrons, and therefore can not transport electricity or heat.
Electrical conductivity is the movement of electrically charged particles, from one transmission medium to another. In the simplest and clearest way: it is the capacity present in an element, medium or physical space to conduct electricity, that is, to transfer electrical energy.

The atoms of metals are joined together forming metal bonds that give a more narrow and stable structure to the metal itself. These liberated atoms form a kind of electron cloud, which conducts electricity with great ease. When an electric field is applied to the material, the electrons of the material begin to flow from one end of the metal to another freely. The same applies to heat in thermal conductivity.
