The flow of electricity is called current. Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators. The tile is a good heat conductor so it moves heat away from your feet while the carpet is a good heat insulator so it does just the opposite of the material that is the conductor. Carpet is not conductive, neither is concrete or dry wood. A flow of electricity is caused by a flow of electrons. Only materials that form electron clouds and those with free ions in aqueous states can conduct electricity.

An ionic compound can conduct electricity when a it is dissolved in water b its crystals are ground into powder c it is in solid form d it is heated to just below its melting point
Ionic compounds can be readily dissolved in water because the high dielectric constant of water screens and decreases the force between the oppositely charged ions.
