Answer: Nuclear Fission
Explanation:
Nuclear fission reactions are one of the nuclear reactions in which heavier nuclei splits into two or more lighter nuclei. In these reactions, neutrons are released with a large amount of energy.
General equation for nuclear fission reactions is given by:
![_Z^A\textrm{X}\rightarrow _(Z-U)^(A-V)\textrm{Y}+_U^V\textrm{W}+3_0^1n+\text{Energy}](https://img.qammunity.org/2019/formulas/physics/high-school/v999b30xl2o6m3yhm9n1crpzviwit2ogd6.png)
Nuclear fusion reactions are one of the nuclear reactions in which two or more lighter nuclei combines to form heavier nuclei. In these reactions, large amount of energy is released.
