A mass spectrometer analyzed neon atoms and found the natural element was composed of two isotopes, neon 20 and 22 by Francis William Aston, physicist from Cambridge University, Cambridge, England in 1919. Aston received the Nobel Prize in Chemistry in 1922 for inventing the mass spectrograph designed to separate atoms of varying mass.
