WebJul 25, 2009 · Cathode Rays. The detection of cathode rays was a by-product of the investigation of the discharge of electricity through rarefied gases. The latter phenomenon had been studied since the early eighteenth century. By the middle of the nineteenth century it was known that the passage of electricity through a partly evacuated tube produced a … WebAug 25, 2024 · The charge of an electron is sometimes referred to as the elementary charge and usually denoted by e. The elementary charge is a fundamental physical constant and as of May 2024, its value is defined to be exactly 1.602176634 × 10 − 19 C. Since the charge of an electron was now known due to Millikan’s research, and the charge-to-mass ratio ...

WebJan 9, 2024 · The British physicist Joseph John (J. J.) Thomson (1856–1940) performed a series of experiments in 1897 designed to study the nature of electric discharge in a high-vacuum cathode-ray tube, an area being investigated by many scientists at the time. Thomson interpreted the deflection of the rays by electrically charged plates and magnets …

His 1897 experiment on cathode rays is generally regarded as the “discovery” of the electron. The purpose of J.J. Thomson’s experiments was clearly stated in the introduction to his 1897 paper.
WebJ.J. Thomson discovered the electron in 1897 and led the Cavendish Laboratory into a world-class research institution. His work opened the field of subatomic physics to experimental investigation and helped unravel the inner workings of the atom. He developed the "plum pudding" model of the atom.
