The mass number (symbol A), also called nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. It determines the atomic mass of atoms. Because protons and neutrons both are baryons, the mass number A is ... Thus the atomic number increases by 1 (Z: 67) and the mass number ...
