(i) There are two kinds of charge. As a matter of convention, charge of a proton is taken as positive and that of an electron is taken as negative.
(ii) Like charges repel each other, while unlike charges attract each other.
(iii) Charge is quantized. Charge on any object is integral multiple of electronic charge. i.e.; q = ± ne, where n = 1, 2 ......., e = 1.6 x 10-19 coulomb (SI unit of change is coulomb).
(iv) Charge is conserved. In all types of phenomena, for an isolated system, total charge is conserved.
