1 янв 1897 г. - J.J. Thomson Discovered The Electron

Описание:

1834 Michael Faraday had coined the word io to account for the charged particles that are attracted positively or negatively to electrodes.

1891 George Johnstone Stoney coined the word electrons represent the fundamental unit of electric charge

Cathode Ray tube allowed cathode rays travel through air rather than usual vacuum to see how far as they could before they were stopped. This suggested the particle within the cathode rays were smaller than what people thought atoms would be. Using a variety of experiments he figured out the rays were negatively charged, at least 1000 ties lighter than a hydrogen atom and all of the rays were identically charged and had identical mass. He used the name electron coined by Faraday
