Discovery of the Electron: Cathode Ray Tube Experiment

WebAs you know, all matter is made of atoms, and atoms are the smallest pieces of chemical elements. In other words, an atom is the smallest particle that displays all the properties of a chemical element. Hydrogen, oxygen, and gold are all examples of elements. Atoms consist of a nucleus and an electron cloud, as illustrated in Figure 1. On 22 December 1884, Thomson was appointed Cavendish Professor of Physics at the University of Cambridge. The appointment caused considerable surprise, given that candidates such as Osborne Reynolds or Richard Glazebrook were older and more experienced in laboratory work. Thomson was known for his work as a mathematician, where he was recognized as an exceptional tale…
