How is nuclear fusion different from nuclear fission?

• In fusion, the product is a larger atomic nucleus.
• Fission produces energy but fusion does not.
• Fusion produces energy but fission does not.
• In fission, the product is a larger atomic nucleus.

What are some of the outcomes of nuclear fusion?

• Produce larger materials from the collision of smaller materials.
• Release energy.
• Produce smaller materials from the collision of larger materials.
• Produce larger materials from the collision of smaller materials & Release energy

In nuclear fusion, smaller atoms are forced together to create larger atoms. Does this process release, absorb or maintain energy?

• Absorb energy
• Maintain energy
• Release energy

In this example of nuclear fusion, the products contain an expelled __________ which also contributes to the release of energy.

• helium
• neutron
• proton
• electron

What is not produced when light elements undergo nuclear fusion?

• Heavier elements
• Energy 
• Lighter elements
• Light

Where does fusion occur naturally?

• Underwater
• All around us
• In the radioactive waste
• In stars
