alleryThe process in which a heavy nucleus splits into two smaller nuclei with release of energy and neutrons is called
Anuclear fission
Bnuclear fusion
Calpha decay
Dbeta decay
Answer & Solution
Correct answer: A. nuclear fission
1. Splitting of a heavy nucleus into two lighter ones is nuclear fission.
2. It releases a large amount of energy plus a few neutrons.
3. Fusion is the opposite: light nuclei combining into a heavier one.
