All matters are made up of tiny particles

called _____

Materials which conduct electricity are called __________

In a _______ atom¸ negative charges are equal to

positive charges

__________ hinder the free flow of electrons from one particle of the element to another. If we transfer some amount of charge to an insulator, the charge remains at the initial location and does not distribute across the surface.
