The energy which is required to split a nucleus into its discrete neutrons and protons is said to be nuclear binding energy.
Using the formula for nuclear binding energy:
E = Δmc²
where,
E = nuclear binding energy
Δm = mass defect
c = speed of light
Substitute the given value of mass defect and speed of light in above formula:
E = [tex]1.643 \times 10^{-28} kg\times(3 \times 10^{8})^{2}m^{2}/s^{2}[/tex]
E = [tex]14.787\times 10^{-12} kgm^{2}/s^{2}[/tex]
[tex]kgm^{2}/s^{2}[/tex] = Joule.
E= [tex]1.48\times 10^{-11} J[/tex]
Thus, nuclear binding energy of an atom is [tex]1.48\times 10^{-11} J[/tex].
