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. Average atomic mass = f 1 M 1 + f 2 M 2 +… + f n M n where f is the fraction representing the natural abundance of the isotope and M is the mass number (weight) of the isotope. The average atomic mass of an element can be found on the periodic table, typically under the elemental symbol. Atomic Mass - YouTube. Grammarly | Work Efficiently From Anywhere. Watch later. Share.
