2019-07-01 · The difference between atomic weight and atomic mass became known when F.W. Aston, the inventor of the mass spectrometer (1927) used his new device to study neon. At that time, the atomic weight of neon was believed to be 20.2 amu, yet Aston observed two peaks in the mass spectrum of neon, at relative masses 20.0 amu and 22.0 amu. Definition of Atomic Weight. The Atomic weight is defined as the average atomic mass of isotopes of an element in a given sample. It is the weighted average atomic mass calculated using the relative abundance of isotopes of an element.
