Whose discovery made it possible to measure very large atoms and molecules by mass spectrometry?
ChemistryAtomic Structure
Quick Answer
J. J. Thomson is associated with early mass spectrograph work in 1912 and the idea of isotopes. His studies helped show that atoms of the same element can have different masses.
The Full Story
J. J. Thomson’s work with positive rays and early mass analysis in the 1910s helped open the door to identifying isotopes. He showed that neon, for example, exists in forms with different masses, even though the chemical element is the same. This was a major shift in chemistry because it proved atomic weight could vary within one element. The development of mass spectrometry later became an essential tool for chemistry, physics and geochemistry.
