Nuclear fusion and fission reaction

Nuclear fusion releases energy when:

• heavy ions fuse together
• very light nuclei fuse together
• uranium splits into two fragments
• uranium emits a neutron

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
