Difference between fusion reaction and fission reaction.
Explanation:
Fission reaction produce energy while fusion reaction absorb energy.This happens because fission reaction deals with the breakdown of one larger nucleus which result in the generation or liberation of energy.Whereas Fusion reaction combines two smaller atomic nuclei,as a result of which it requires energy for the joining of two smaller atomic nuclei into a larger nucleus.
