Detailed explanation-1: -J.J. Thomson’s experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged “soup."

Detailed explanation-2: -Thomson Experiment – The Discovery of Electron. The Cathode ray experiment was a result of English physicists named J. J. Thomson experimenting with cathode ray tubes. During his experiment he discovered electrons and it is one of the most important discoveries in the history of physics.

Detailed explanation-3: -In 1897 Thomson discovered the electron and then went on to propose a model for the structure of the atom. His work also led to the invention of the mass spectrograph.

Detailed explanation-4: -Electrons were discovered as the constituents of cathode rays in 1897 by British physicist J. J.Thomson. He showed the rays were composed of a previously unknown negatively charged particle, which was later called the electron.

Detailed explanation-5: -During the 1880s and ‘90s scientists searched cathode rays for the carrier of the electrical properties in matter. Their work culminated in the discovery by English physicist J.J. Thomson of the electron in 1897.
