Nuclear Fission and Fusion

The splitting of a nucleus into smaller nuclei is

• fusion
• fission
• half-life
• gamma radiation

Takes two small nuclei and combines them into a larger nucleus

• fission
• fusion

Where does fusion occur naturally?

• Underwater
• All around us
• In the radioactive waste
• On the sun

An example of an uncontrolled fission reaction is _______________

Why do scientists most want to learn more about fusion?

• To win the Nobel prize
• To make energy for people to use
• To destroy the world
• To know more about stars

_________ happens naturally due to an unstable nucleus.
