WebThomson conjectured that the electron was a fundamental building block of matter or atoms, and along with his colleagues at Cambridge attempted to build upon his discovery in order to model atomic structure with theoretical speculations and extensive experimental investigations, particularly scattering experiments. WebThomson's measurement convinced him that cathode rays were particles, which were later identified as electrons, and he is generally credited with their discovery. The CODATA recommended value is − e / me = −1.758 820 010 76(53) × 1011 C⋅kg−1. [2] CODATA refers to this as the electron charge-to-mass quotient, but ratio is still commonly used.

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 ...
