The binding energy of a nucleus is the amount of energy needed to .

The binding energy of a nucleus is the amount of energy needed to disassemble the nucleus.

Explanation:

The binding energy is defined as the amount amount of energy spent to separate particles from the system of particles. It is also called as separation energy.

The binding energy can be used to separate electron from  nuclei in atoms, to ions and atoms in crystals.

The nuclear binding energy is the minimum amount of energy required to separate the nucleus into its components.The components of nucleus are proton and neutrons . The proton and neutron together is called as nucleons.

The nuclear binding energy is very much greater than electron binding energy  of the lighter atoms.

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.
