Discovery of cathode electrone & proton.

1.	Discovery of cathode electrone & proton.
Answer» 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. ... These protons ADD the overall positive charge of an ATOM.
