WebFeb 19, 2016 · One way to do it is to use a mass spectrometer. A variation of this was done in World War II, to separate Uranium isotopes. You can separate them because they have different masses. Uranium-238 has more neutrons than Uranium-235. Therefore, it has more mass. Let's see how my mass spectrometer works. The first step is ionization. WebOct 1, 2024 · Francis William Aston (1877-1945) Thomson had already been awarded the Nobel Prize in Physics, in 1906, for his work in gas discharge tubes. He had correctly deduced that cathode rays were a stream of negatively charged sub-atomic particles – the electron. He then turned his attention to the simultaneously produced positive rays.
