WebScientists can measure relative atomic masses very accurately, however, using an instrument called a mass spectrometer. The technique is conceptually similar to the one Thomson used to determine the mass-to-charge ratio of the electron. First, electrons are removed from or added to atoms or molecules, thus producing charged particles called … WebAtomic mass is most conveniently described by the atomic mass unit, which is 1/12 of the mass of a carbon-12 atom. This means that each proton and each neutron contribute 1 amu to the mass of an atom, which makes it very easy to calculate. You can also use this to account for different isotopes.
