Matter is made up of particles called atoms which contain negatively charged particles called electrons that orbit around a nucleus of positively charged protons and neutral neutrons. An atom in its general state is balanced. An electrified state is that which is unbalanced due to the removal or addition of electrons. An atom in this state is ionised. These are two types of charges ( and the only ones ) which are produced by friction between different materials. In charging by friction, some electrons from the surface atoms of one object are transferred to the surface of another atom. Charge is not destroyed only transferred.
