Assume that the nuclear binding energy per nucleon ( B A ) versus mass number ( A ) is as shown in the figure. Use this plot to choose the correct choice given below.

Options

  1. AFusion of two nuclei with mass numbers lying in the range of 1 < A < 50 will release energy.
  2. BFusion of two nuclei with mass numbers lying in the range of 51 < A < 100 will consume energy.
  3. CFission of a nucleus lying in the mass range of 100 < A < 200 will release energy when broken into two equal f
  4. DFission of a nucleus lying in the mass range of 200 < A < 260 will release energy when broken into two equal f

Correct answer

D. Fission of a nucleus lying in the mass range of 200 < A < 260 will release energy when broken into two equal f

Step-by-step solution

In fusion, two or more lighter nuclei combine to make a comparatively heavier nucleus. In fission, a heavy nucleus breaks into more than one comparatively lighter nucleus. Further, energy will be released in a nuclear process if total binding energy increases. Therefore Correct option is that the fission of a nucleus lying in the mass range of 200 < A < 260 will release energy when broken into two equal fragments.
