What did JJ Thomson discover?
Did JJ Thomson use cathode rays?
Thomson determined that charged particles much lighter than atoms, particles that we now call electrons made up cathode rays. Cathode rays form when electrons emit from one electrode and travel to another. The transfer occurs due to the application of a voltage in vacuum.
Sep 7, 2017 · Why did J. J. Thomson discover the electron in 1897? Well, according to Thomson: “the discovery of the electron began with an attempt to explain the discrepancy between the behavior of cathode rays under magnetic and electric forces [4] .”

Feb 13, 2024 · Renowned for his discovery of the electron, Thomson’s work fundamentally altered our understanding of atomic structure, revealing an intricate world of subatomic particles beneath the seemingly solid facade of matter. Thomson’s contributions extended beyond the laboratory.
May 16, 2022 · Thomson did more than discover electrons; his method, which involved accelerating particles between electrodes, kicked off a new way to study the subatomic world, using accelerators and...
Nov 27, 2015 · J. J. Thomson discovered the electron in 1897 while performing experiments on electric discharge in a high-vacuum cathode ray tube. He interpreted the deflection of the rays by electrically charged plates and magnets as "evidence of bodies much smaller than atoms."
On 30 April, 1897, J. J. Thomson announced the results of his previous four months' experiments on cathode rays. The rays, he suggested, were negatively charged subatomic particles. He called the particles ‘corpuscles’. They have since been re-named ‘electrons’ and Thomson has been hailed as their ‘discoverer’.
Nov 21, 2023 · J.J. Thomson's cathode ray tube experiment discovered the subatomic particle the electron. Prior to the experiment, it was not known that atoms were composed of further particles.
