Explain the terms 'mass defect' and 'binding energy'. How are they related ? Draw binding energy curve.

Text Solution

Verified by Experts

Mass defect : It is the difference between the sum of the masses of the nucleons/constituents of the nucleus and the nuclear mass.
Binding energy : The minimum energy required to break the nucleus into its constituent nucleons/ particles.
Binding energy `=(Deltam)931MeV`
Binding energy = (Am) 931 MeV Binding energy is energy equivalent to mass defect.
Binding energy curve:
