15) Why is critical mass important for a fission chain reaction? (bonus) *
• It keeps neutrons from escaping the sample.
• It keeps neutrons from being absorbed by other isotopes.
It allows neutrons to be absorbed by other fissionable nuclei.
• It provides enough fuel to make enough energy.

) It allows a self-sustaining nuclear reaction to occur, as each fission event releases additional neutrons that can go on to cause more fission events in a chain reaction.
