Explain the terms 'mass defect' and 'binding energy'. How are they related ? Draw binding energy curve. |
|
Answer» Solution :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:
