WebThe mass number (symbol A, from the German word Atomgewicht [atomic weight]), [1] also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. It is approximately equal to the atomic (also known as isotopic) mass of the atom expressed in atomic mass units. WebMar 24, 2024 · Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number. An atom of iron has 26 protons in its nucleus; therefore the atomic number of iron is 26. In the symbol representing a particular nuclear or atomic species, the atomic number may be indicated as a left subscript.
