WebbIt represents the number of positively charged particles, called protons, present in the atom's nucleus. Since the atom is electrically neutral, the atomic number also represents the number of negatively charged particles, called electrons, orbiting around the nucleus. In a neutral atom, the number of electrons is equal to the number of protons. The mass number (symbol A, from the German word Atomgewicht [atomic weight]), 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. Since protons and neutrons are both
