Electrical nature of matter (Electric Charge)
All matter consists of atoms.
Electrical nature of matter (Electric Charge)
All matter consists of atoms. All atoms consists of protons (+ve charge), neutrons (0 charge) & electrons
(−ve charge).

All matter consists of atoms. All atoms consists of protons (+ve charge), neutrons (0 charge) & electrons
(−ve charge).
Normally, number of protons = number of electrons, and the matter is said
to be electrically neutral. Charge is also a basic property of matter like mass.

Electric Charge...Contd
SI Unit is Coulomb (C)
Charge on an e−^ = − 1. 602 × 10 −^19 C.
1 C = 6. 25 × 1018 e−s
