Nuclear binding energy is the energy required to split a nucleus of an atom into its components parts: protons and neutrons or collectively the nucleons. The binding energy of nuclei is always a positive number since all nuclei require net energy to separate them into individual protons and neutrons.
Mass defect:- Nuclear binding energy accounts for a noticeable difference between the actual mass of atom's nucleus and its expected mass based on the sum of the masses of its non-bound components.
