Discovery of proton neutron electron
WebThe electron neutrino ( ν e) is an elementary particle which has zero electric charge and a spin of 1 ⁄ 2.Together with the electron, it forms the first generation of leptons, hence the name electron neutrino.It was first hypothesized by Wolfgang Pauli in 1930, to account for missing momentum and missing energy in beta decay, and was discovered in 1956 by a … WebProtons and neutrons occupy the centre nucleus, whereas electrons orbit specific orbits around the nucleus. Scientists discovered this group of subatomic particles in the nineteenth and twentieth centuries. In the year 1932, British scientist Sir James Chadwick discovered neutrons.
