Well lets first define the word conductive as the ability to freely pass the flow of electrons from one shell to another. An insulator is a material that is adverse to the flow of electricity across it and will not cause the electrons within it to cascade the valance shell and transfer electricity.

A substance is a conductor if it allows electric current to flow easily through it due to the presence of free electrons that can carry the charge. An insulator, on the other hand, restricts the flow of electric current due to its lack of free electrons or the strong binding of electrons in the material. The conductivity of a substance depends on its atomic structure and the availability of free charges.
