Explanation:
There are two classes of nuclear reactions which are:
- Nuclear fission
- Nuclear fusion
In nuclear fission, a radioactive isotope which has a heavier nucleus spontaneously disintegrates(breaks up) into 2 lighter nuclei and several neutrons with a large release of energy.
A nuclear fusion occurs by the combination of small atomic nuclei into larger ones with the release of a large amount of energy.
I hope you can make the best choice from this explanation.
