WebThe Discovery of the Electron (J. J. Thomson) In 1897, J. J. Thomson found that the cathode rays can be deflected by an electric field, as shown below. By balancing the effect of a magnetic field on a cathode-ray beam with an electric field, Thomson was able to show that cathode "rays"are actually composed of WebThree experiments led him to this.: irst, in a variation of an 1895 experiment by Jean Perrin, Thomson built a cathode ray tube ending in a pair of metal cylinders with a slit in them. These cylinders were in turn connected to an electrometer, a device for catching and measuring electrical charge. Perrin had found that cathode rays deposited an ...

WebThomson made this discovery when his research student Francis Aston fired ionized neon through a magnetic and electric field – i.e. he used a mass spectrometer – and observed two distinct deflections. Thomson concluded that neon exists in two forms whose masses are different – i.e. isotopes. WebHe discovered the electron through his famous cathode ray tube experiment, where he noticed and measured the deflection of the ray (composed of electrons) caused by an electric field. He concluded that there must be a particle with a very small mass but a comparatively large charge, which we now know as the electron.
