The British physicist Joseph John “J. J.” Thomson (1856–1940) performed a series of experiments in 1897 designed to study the nature of electric discharge in a high-vacuum cathode-ray tube, an area being investigated by many scientists at the time. Thomson interpreted the deflection of the rays by electrically charged plates and magnets ...

J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup."

J. J. Thomson autobiography. Joseph John Thomson was born on December 18, 1856 in Cheetham, a suburb of Manchester. His father was a bookseller and publisher. It was originally intended that he should be an engineer, and, at the age of fourteen, he was sent to Owens College - later Manchester University - until there was a vacancy for an ...

J. J. Thomson, the Discovery of the Electron, and the Study of Atomic StructureOverviewLate in the nineteenth century physicists were working hard to understand the properties of electricity and the nature of matter. Both subjects were transformed by the experiments of J. J. Thomson, who in 1897 showed the existence of the charged particles ...

J. J. Thomson 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

Sir Joseph John "J.J." Thomson, OM, FRS (18 December 1856 – 30 August 1940) was a British physicist and Nobel laureate. He discovered the electron and isotopes, and invented the mass spectrometer. He was awarded the Nobel Prize in Physics in 1906 for his discovery of the electron and his work on the conduction of electricity in gases. John ...
