sir jj thomsons was a brialiant english physics scientist, he observed the cathod in atom, later called electron, by CRT CATHOD RAY TUBE
Thomson set out to prove that the cathode rays produced from the cathode were actually a stream of negatively charged particles called electrons.
J.J. Thomson's ideas were called the plum-pudding model. This model described how electrons were evenly distributed throughout the atom.
