Answer:
Nuclear fission
Step-by-step explanation:
This reaction is called a nuclear fission reaction. In this reaction, a radioactive decay process occurs in which a heavy nucleus spontaneously disintegrates into two lighter nuclei and several neutrons, with the release of a large amount of energy.
- The imbalance between the number of neutrons and protons is responsible for this spontaneous disintegration.
- Until a stable daughter cell forms, the reaction proceeds.
