Each12C atom has six protons and six neutrons in its nucleus, adding up to an atomic mass of 12 AMU.Electronshave a low mass, so they are assumed to have a negligible effect. Consequently, the nucleus accounts for almost the entire mass of the atom of any element, which means that a ...
John Daltonfirst suggested a means of expressing relative atomic mass in 1803. He proposed the use of hydrogen-1 (protium). Wilhelm Ostwald suggested that relative atomic mass would be better if expressed in terms of 1/16th the mass of oxygen. When the existence of isotopes was discovered in...
However, the nuclei of atoms are smaller than the wavelengths of visible light so they can't be observed by normal means. It is also difficult to measure the mass of an individual atom. Atoms are so small that grams are completely impractical to use to describe their masses. For example,...
