Which of these statements correctly describes how the chain reaction occurs in nuclear fission.

• Uranium releases electrons to create   electricity
• When a nuclear fission reaction occurs, the electrons 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
•  Protons and neutrons change to electrons because the nuclei are so big

What is Half-life?

• The amount of time it takes for some of the nuclei in a sample of the isotope to decay
• The amount of time it takes for half the electrons in a sample of the isotope to decay
• The amount of time it takes for half the nuclei in a sample of the isotope to decay
