  • The electrons possess negligible mass. They do not contribute much to the mass of an atom.
  • Therefore, the entire mass of an atom is supposed to be present in the nucleus which consists of protons and neutrons, which are collectively called as nucleons.

Hence,

Approximate atomic mass in Daltons is numerically equal to the number of nucleons in the atom.
