WebWhile controversial at first, Thomson's discoveries were gradually accepted by scientists. Eventually, his cathode ray particles were given a more familiar name: electrons. The … WebIn 1897, J.J. Thomson discovered a new lighter particle than hydrogen, which was dubbed"electron." Hydrogen was considered a unit of measurement of atomic weight. Until that moment, the atom was the smallest division of matter. In this sense, Thomson was the first to discover negatively charged corpuscular subatomic particles.
Web30 jul. 2024 · J.J. Thomson made a detailed study of the discharge of electricity through gases under very low pressure. This experiment was performed using a cathode ray tube (Crooke’s tube). It consists of a glass tube connected to two metal electrodes at two ends. There is a side tube connected to a vacuum pump to reduce pressure. Web19 apr. 2024 · 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.
