Fission vs Fusion

Takes two small nuclei and combines them into a larger nucleus

• fission
• fusion

The splitting of a nucleus into smaller nuclei is

• fusion
• fission
• half-life
• gamma radiation

How do nuclear power-plants work?

• Fusion
• Half-life
• Fission
• Fusion or fission

Where does fusion occur naturally?

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

Which atoms combine together during fusion reaction on the sun?

• Helium and Hydrogen atoms
• Hydrogen atoms
• Hydrogen and Lithium atoms
• Hydrogen and Carbon atoms

What does it mean that fusion is a "chain reaction?"

• many steps or mini-reactions in the process
• long chains of elements form in a row

Do all stars make energy through fusion?

• Yes
• No
• Just our sun
• Only large stars

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

What is a benefit of nuclear fission?

• The ability to absorb energy
• The ability to release tremendous amounts of energy
• The ability to produce more energy than nuclear fusion
• There are no beneficial aspects of nuclear fission

Very high temperature and pressure is required for:

• Fission
•  Fusion
• Radioactive Decay
