Answer 2

Answer:

packing fraction

Explanation:

The packing fraction is the mass defect per nucleon. It is the ratio of mass defect 'Δm' to the mass number 'A'. The total energy required to liberate all the nucleons from the nucleus (i.e. separating the protons and neutrons of the nucleus infinite distance apart) is called Nuclear Binding Energy
