- 3. Multiple ChoiceWhich of these statements correctly describes how the chain reaction occurs in nuclear fission.Uranium releases electrons to create electricityWhen a nuclear fission reaction occurs, the electrons emitted can strike other nuclei in the sample, and cause them to splitWhen a nuclear fission reaction occurs, the neutrons emitted can strike other nuclei in the sample, and cause them to splitProtons and neutrons change to electrons because the nuclei are so big
