Answer

The mass number is a whole number approximation of the atomic mass in atomic mass units since the mass of the proton as well as the mass of the neutron is approximately equal to 1 a.m.u. and the mass of the electron is negligible. Hence, the mass number is slightly less than the actual atomic mass.
