Key characteristics of nuclear fission (concise):
- A heavy nucleus (e.g., U‑235 or Pu‑239) splits into two (or more) lighter nuclei (fission fragments).
- Several free neutrons are emitted.
- A large amount of energy is released (mass defect converted to energy via E=mc²).
- The emitted neutrons can induce further fissions, allowing a chain reaction.
- The fission products are typically highly radioactive.
If you meant a single short answer: fission is the splitting of a heavy nucleus into lighter nuclei with release of energy and neutrons.
