Question

what is quantization of charge

Answer 1

Charge only comes incountable numbers. The smallest amount of charge that has ever been observed isthe charge on the electron and/or the charge on the proton (both the same amount, but opposite type). Hence the term"quantization of charge." Quantum or"quantized" means that it is numbered or integer-countable (can come in -1, 0, 1, 2, 3, etc. but not 1.5 or pi, etc), and a quantum is essentially one of those quantized objects. The total charge on a charged object is therefore thenumber of individual charges, all of which are either electrons orprotons, multiplied bythe charge on one of them. This explains the existence of the following equation:

Answer 2

So negative charge means that there is an excess of electrons while positivecharge is a deficiency of electrons.Quantization of charge means that when we say something has a givencharge, we mean that that is how many times the charge of a single electron it has.
