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.” WebA cathode made of a wire filament heated red hot by a separate current passing through it would release electrons into the tube by a process called thermionic emission. The first true electronic vacuum tubes, invented in 1904 by John Ambrose Fleming, used this hot cathode technique, and they superseded Crookes tubes.
Web30 de jul. de 2024 · Discovery of Electrons: Electrons were the first of sub-atomic particles to be discovered, by J.J. Thomson in 1859. J.J. Thomson made a detailed study of the discharge of electricity through gases under very low pressure. This experiment was performed using a cathode ray tube (Crooke’s tube). Web30 de abr. de 2024 · Nor did Thomson choose to call his subatomic particles by a name that was already in use: the electron. In 1874, the Irish physicist George Johnstone Stoney proposed electrine for the unknown subatomic particle, later changing it to electron in 1891.
