In a fission nuclear reaction , a heavy nucleus breaks up into smaller nuclei whereas in another nuclear reaction two or more than two possibly nuclei are fused to form a heavy nucleus This nuclear reaction is called ?

Question

Accepted Answer

Fusion nuclear reaction E. None of these. Fusion nuclear reaction is correct because it describes the process of two or more light nuclei fusing into a heavier one. Chemical Reaction involves rearranging electrons in atoms, not changing the nucleus. Fission nuclear reaction describes a heavy nucleus breaking up, which is the opposite process mentioned for fusion. None of these would be incorrect as D accurately names the described process.
