Identify the electrical properties of materials that are highly conductive and those that are used in insulation. Use one or two sentences to complete your answer

This question is incomplete

Explanation:

However, materials that are highly conductive have the capacity to allow heat and electricity to pass through them. This occurs because they have electrons that flow easily in them, these electrons serve as carriers of heat and electric current in these materials. It should be noted here that not only solid metals (like silver, aluminium and copper) are good conductors of electricity, liquid solution such as aqueous NaCl are also good conductors of electricity because of the same movement of electrons (which is being transferred during bonding as charges) in the liquid.

Invariably, materials that are poor conductors of heat and electricity do not have electrons moving freely in them. Examples are sand, rubber and plastic.
