Ten fun facts about Joseph J. Thomson
Fact 1Fact 4
Joseph J. Thomson was born on 18 December 1856 in England and died on 30 August 1940.
In 1897, Thomson exhibited that cathode rays were comprised of a previously unknown negatively charged particle, and thus is known for the discovery and identification of the electron.
Thomson is also recognized as the finder of the first evidence for isotopes of a stable non-radioactive element as a portion of his examination into the structure of canal rays (positive ions) and with the creation of the mass spectrometer.
Thomson was given the 1906 Nobel Prize in Physics for the finding of the electron and for his study on the conduction of electricity in gases.Fact 5
In 1905 Thomson revealed the natural radioactivity of potassium and in 1906 he verified that hydrogen had only one electron per atom.Fact 6
He won the Royal Medal (1894), Elliott Cresson Medal (1910), Franklin Medal (1922), Copley Medal (1914) and Hughes Medal (1902).Fact 7
In 1991 the symbol ‘th’ was put forward in mass spectrometry as a unit to measure mass to charge ratio.Fact 8
His separation of neon isotopes by their mass was the initial example of mass spectrometry, which was consequently enhanced and advanced into a general process by F. W. Aston and by A. J. Dempster.Fact 9
He is buried in Westminster Abbey, close to the grave of Sir Isaac Newton.Fact 10
On 12 June 1884, Thomson was chosen a Fellow of the Royal Society and was later the President of the Royal Society from 1915 to 1920. Go to more people facts ❯
