Multiple Choice

What is a chain reaction?

• When electrons travel are emitted causing electricity
• When a nuclear fission reaction occurs, the protons emitted can strike other nuclei in the sample, and cause them to split
• When a nuclear fission reaction occurs, the neutrons emitted can strike other nuclei in the sample, and cause them to split
• When a nuclear fission reaction occurs, the electrons emitted can strike other nuclei in the sample, and cause them to split
