about 35 different subatomic particles are known but the three particles namely electron, proton and neutron are regarded as the fundamental particles. We shall now take up the brief study of these fundamental particles. The existence of electrons in atoms was first suggested, by J.J. Thomson, as a result of experimental work on the conduction of
