Model answer
What a good answer should say
- A process where a single fission event causes multiple fission events.
Explanation
Why this works
A chain reaction occurs when the neutrons released from one fission event induce further fission events in nearby nuclei, leading to a self-sustaining series of reactions. This is essential for the operation of nuclear reactors and atomic bombs.
