Question

This question contains Statement-1 and statement-2. Of the four choices given after the statements, choose the one that best describes the two statements.

Statement-1:
Energy is released when heavy nuclei undergo fission or light nuclei undergo fusion and

Statement-2:
For heavy nuclei, binding energy per nucleon increases with increasing Z while for light nuclei it decreases with increasing Z.

Accepted Answer

Statement-1 is true, Statement-2 is false. Statement-1 is accurate as energy is indeed released during fission of heavy nuclei and fusion of light nuclei. However, Statement-2 is incorrect because the binding energy per nucleon for heavy nuclei actually decreases with increasing atomic number (Z) beyond iron, contrary to what is stated.
