J.J. Thompson discovered it in 1897.
In 1896, the British physicist J.J. Thomson,with his colleagues John S. Townsend and H.A. Wilson performed experiments indicating that cathode rays really were unique particles,rather than waves,atom or molecules believed earlier.Thomson made good estimates of both the charge e and the mass m,finding that cathode ray particles,which he called "corpuscles,"had perhaps one thousand of the mass of the least massive ion known : Hydrogen (Atomic Mass : 1u).He showed that their charge to mass ratio,e/m was independent of cathode material.He further showed that the negatively charged particles produced by radioactive materials, by heated material and by illuminated materials were universal.The name electron was again proposed for these particles by the Irish physicist George F. Fitzgerald, and name has since gained universal acceptance.

Who and when discovered the electron scanning microscope?
Charles Oatley in 1952 discovered the electron scanning microscope, but Max Knott created the first prototype of the SEM in 1935.
The electron was discovered by Goldstein in 1886?
Thomson, Townsend and Wilson are credited for the discovery of electron in 1991.
Who discovered that atoms contain subatomic particles?
J.J. Thomson discovered the first subatomic particle, the electron, in the late 19th century through his experiments with cathode rays. This discovery led to the understanding that atoms contain subatomic particles.
When electron neutron and proton were invented?
They were never invented. They were discovered by various people at various times: Ernest Rutherford effectively discovered protons, around 1910, with his famous gold film experiment. He is usually "officially" credited with the discovery for his work in 1919. The electron was discovered in 1897 by J.J. Thomson. The neutron was discovered in 1932 by James Chadwick.
Who discovered binomial particles?
Binomial particles like protons, neutrons, and electrons were discovered by multiple scientists. The electron was discovered by J.J. Thomson in 1897, the proton was discovered by Ernest Rutherford in 1919, and the neutron was discovered by James Chadwick in 1932.
