Answer 1

The binding energy of a nucleus

1. It may be defined as the amount of energy needed to separate a nucleus into its individual nucleons and hence is a measure of the stability of the nucleus.
2. The mass of a ${}_{}{}^2\mathrm{H}$ atom is less than the sum of the masses of a proton, a neutron, and an electron by $0.002388amu$; the difference in mass corresponds to the nuclear binding energy.
3. The larger the value of the mass defect, the greater the nuclear binding energy and the more stable the nucleus.
