Question

Binding energy per nucleon vs mass number curve for nuclei is shown in the figure. W, X, Y and Z are four nuclei indicated on the curve. Identify which of the following nuclei is most likely to undergo

1. Nuclear Fission
2. Nuclear Fusion.

Justify your answer.

Answer 1

1. Nuclear fission - W
   Reason: As W has binding energy less than Y and X and the nucleus is larger in size.
2. Nuclear fusion - Z
   Reason: As Z has binding energy that is less than Y and X and the nucleus is smaller in size.
