Definition of Nuclear Fusion



Nuclear fusion is a type of reaction that involves two or more than two atomic nuclei and these nuclei then tend to give rise to different atomic nuclei along with the release of some subatomic particles i.e., neutrons, protons, electrons, etc. The release or absorption of energy depends upon the difference in the masses of the reactant and the product molecules.

 


This difference arises due to the fact that the atomic binding energy of the nuclei before and after the reaction does not remain the same. Those fusion processes generally release energy which tends to produce atomic nuclei lighter than iron-56 and nickle-62. Hence, it is said that the lighter elements like H, He, etc. undergo fusion reactions.
