Question

There are large numbers of charged particles in most objects. Why, then, don't most objects exhibit static electricity?

Answer 1

No charge is actually created or destroyed when charges are separated as we have been discussing. Rather, existing charges are moved about. In fact, in all situations the total amount of charge is always constant. This universally obeyed law of nature is called the law of conservation of charge

When enough energy is present, it can be converted into matter. Here the matter created is an electron–antielectron pair. (me is the electron’s mass.) The total charge before and after this event is zero

When matter and antimatter collide, they annihilate each other; the total charge is conserved at zero before and after the annihilation.
