Neutrons released during a fission reaction cause other nuclei to split.

Explanation: In fission, each splitting of a heavy nucleus (like U-235 or Pu-239) releases neutrons that can induce further fissions. If on average at least one neutron from each fission causes another fission, a self-sustaining chain reaction occurs (critical). Fusion does release neutrons in some reactions, but fusion does not typically produce the neutron-driven, self-sustaining sequence described by a fission chain reaction.
