e. mass deficiency

Explanation:

The difference in the nuclei which is composed of the protons and the neutrons and the sum of the mass of the protons and the neutrons is called mass deficiency.

The definition of the mass deficiency can be applied to the whole atom.

The mass difference is equal to released binding energy.
