Question

Nuclear energy released in fission since binding energy per nucleon is

• A. sometimes larger and sometimes smaller
• B. larger for fission fragments than for parent nucleus
• C. same for fission fragments and nucleus
• D. smaller for fission fragments than for parent nucleus

Hint:

Energy is released whenever binding energy per nucleon increases.

Answer 1

The Correct Option is B

Heavy nuclei have lower binding energy per nucleon. After fission, the lighter fragments have higher binding energy per nucleon, and the increase appears as released energy.
