• fission
• 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

This is an example of...

• Fission  reaction
• Fusion reaction
• Decomposition reaction
• Decay

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

An example of an uncontrolled fission reaction is _______________

• Nuclear power plants
• Radio active decay
• Atomic Bomb
• On the surface of the sun

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
