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
