Apr 11, 2024 · subatomic particle. J.J. Thomson (born December 18, 1856, Cheetham Hill, near Manchester, England—died August 30, 1940, Cambridge, Cambridgeshire) was an English physicist who helped revolutionize the knowledge of atomic structure by his discovery of the electron (1897). He received the Nobel Prize for Physics in 1906 and was knighted in 1908.

Feb 2, 2020 · Tomson was born December 18, 1856, Cheetham Hill, near Manchester, England. He died August 30, 1940, Cambridge, Cambridgeshire, England. Thomson is buried in Westminster Abbey, near Sir Isaac Newton. J.J. Thomson is credited with the discovery of the electron, the negatively charged particle in the atom. He is known for the Thomson atomic theory.

Thomson also placed two magnets on either side of the tube, and observed that this magnetic field also deflected the cathode ray. The results of these experiments helped Thomson determine the mass-to-charge ratio of the cathode ray particles, which led to a fascinating discovery − the mass of each particle was much, much smaller than that of any known atom.

Lived 1856 – 1940. J. J. Thomson took science to new heights with his 1897 discovery of the electron – the first subatomic particle. He also found the first evidence that stable elements can exist as isotopes and invented one of the most powerful tools in analytical chemistry – the mass spectrometer. Advertisements.
