Each element is uniquely defined by its atomic number. Atomic mass: The mass of an atom is primarily determined by the number of protons and neutrons in its nucleus. Atomic mass is measured in Atomic Mass Units (amu) which are scaled relative to carbon, 12 C, that is taken as a standard element with an atomic mass of 12. This isotope of carbon.
