It is because they have zero known components or substructures, and because of this, they are considered elementary particles. Discovery of Electrons. In 1897, J.J. Thomson discovered electrons by working on a cathode ray tube.

WebA particle of 200 electron masses is discovered in cosmic rays. While at first physicists thought it was Yukawa's pion, it was later discovered to be a muon. 1938 E.C.G. Stückelberg observes that protons and neutrons do not decay into any combination of electrons, neutrinos, muons, or their antiparticles. The stability of the proton cannot be ... WebOct 19, 2024 · According to him, the charge of a single electron was 1.6 x 10 -19 Coulomb. With Thomson’s mass to charge ratio and charge on a single electron, Millikan calculated the mass of an electron. The mass of the electron is 9.1094 x 10 - ³¹ kg. Thomson was awarded the Nobel prize in 1906 for discovering the fundamental particle electron. WebJ.J Thomson discovered electrons in the year 1897 by performing the cathode ray experiment. He showed that cathode rays are charged particles. The speed of cathode rays is much less than the speed of light. He measured the charge to mass ratio of cathode rays.
