SpletIt 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 … SpletThe total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z.
