The atomic mass of an atom is the sum of the number of protons and neutrons that it has in its nucleus. The mass of protons and neutron varies slightly as is generally taken as 1, and the mass of electrons is taken as 0 as it is very small compared to nucleons.

So to find the number of neutrons you have to subtract the atomic number from the atomic mass.

The mass # is used to calculate the number of nucleons in 1 atom of an element. In order to calculate the # of neutrons you must subtract the atomic number from the atomic mass.
