How did thompson discover electrons
WebFor much of his career, Thomson worked on various aspects of the conduction of electricity through gases. In 1897 he reported that "cathode rays" were actually negatively charged particles in motion; he argued that the charged particles weighed much less than the lightest atom and were in fact constituents of atoms [Thomson 1897a, 1897b ]. WebThomson’s discovery established the particulate nature of electricity. Accordingly, he called his particles electrons. From the magnitude of the electrical and magnetic deflections, …

Dalton thought that atoms were indivisible particles, and Thomson's discovery of the electron proved the existence of subatomic particles. This ushered in a model of atomic structure referred to as the plum …
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.
