Nuclear fusion differs from nuclear fission because nuclear fusion reactions

Nuclear fusion reactions produce more energy.( basic difference)

Explanation:

Nuclear fusion reactions are different from nuclear fusion reactions :- In nuclear fission one heavy and unstable nuclear breaks into two parts(smaller) and produce energy( very high energy than normal reaction). whereas in nuclear fusion two small and unstable nuclei fuse and produce very high amount of energy( even higher than nuclear fusion).
