Nuclear energy

Where did the United States conduct all of its nuclear testing following World War II?

• Faulk Islands

• Marshall Islands

• Markum Islands

• Miller Islands

How do nuclear power-plants work?

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

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

Where does fusion occur naturally?

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

What is a half-life?

• The average time it takes for any element to disappear completely 
• The time it takes for a radioactive atom to lose half its neutrons
• The time it takes for half of any number of radioactive atoms to decay
• The time it takes for a radioactive atom to lose half its electrons 

This is an example of...

• Fission  reaction
• Fusion reaction
• Decomposition reaction
• Combustion

Splitting a uranium atom is called - 

• fission
• fusion

All of the following are problems of nuclear energy except ---

• storage of radioactive fuel
• air pollution
• security concerns
• natural disasters (tsunamis, earthquakes, etc.)

What is an advantage  of nuclear energy?

• radioactive waste
• no air pollution
• we will never run out
• it is the safest way to make energy
