Nuclear Binding Energy

The binding energy of deuteron is and that of is . If two deuterons are fused to form one , ${\mathrm{}}^{}$then the energy released is:
1.
2.
3.
4.

A nucleus ${}_Z{X}^A$ has a mass represented by If and denote the mass of proton and neutron respectively and BE the binding energy, then:

1. $BE=\left[M\right(A,Z)-Z{M}_p-(A-Z\left)M_n\right]c^2$

2. $BE=[Z{M}_p+(A-Z)M_n-M(A,$ $Z\left)\right]c^2$

3. $BE=[Z{M}_p+A{M}_n-M-(A,$ $Z\left)\right]c^2$

4. $BE=M(A,$ $Z)-Z{M}_p-(A-Z)M_n$

The mass of a ${}_3{}^7\mathrm{Li}$ nucleus is less than the sum of the masses of all its nucleons. The binding energy per nucleon of the ${}_3{}^7\mathrm{Li}$ nucleus is near:
1.
2.
3.
4.

A nucleus with mass number breaks into fragments each of mass number The binding energy per nucleon of unfragmented nuclei is while that of fragments is The total gain in the binding energy in the process is:
