Question

what is quantisation of charge

Answer 1

Charge quantization, then, means that charge cannot take any arbitrary values, but only values that are integral multiples of the fundamental charge (charge of proton/electron). For example, in a hydrogen ion, we usually denote it with a positive sign to indicate that there's one proton more than there are electrons.

Answer 2

Answer:

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