What is the name of the scientist who discovered the electron?
The Discovery of the Electrons [edit]. The Electron was discovered in 1896, by the British physicist J. J. Thomson, using a cathode rays while doing discharge tube experiments.Thomson also determined e/m, ratio of the charge e to the mass m of the material particle which constituted these rays.iven the discoveries of electrons in 1897 by Thomson, Rutherford and other scientists decided that a positively charged particle must exist to center the electron to create equally neutral atoms. Thompson proposed the name âpositive raysâ.
