Fission & Fusion

The splitting of a nucleus into smaller nuclei is called

• fusion

• fission

• hydropower

• solar power

This is an example of...

• Fission reaction

• Fusion reaction

• Photovoltaic cell

• Steam turbine

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

• Nuclear Bomb

• On the surface of the sun

The product of nuclear fission includes

• neutrons and electrons
• several nuclei and neutrons
• several nuclei and electrons
• several nuclei and protons

Which of the following is true about nuclear fission?

• The mass of the product is greater than the mass of the original nucleus
• The mass of the product is less than that of the original nucleus
• The mass of the product is the same as the mass of the original nucleus
• The mass of the product is 100 times greater than the original nucleus

What is a chain reaction?

• When electrons travel are emitted causing electricity
• When a nuclear fission reaction occurs, the protons emitted can strike other nuclei in the sample, and cause them to split
• When a nuclear fission reaction occurs, the neutrons emitted can strike other nuclei in the sample, and cause them to split
• When a nuclear fission reaction occurs, the electrons emitted can strike other nuclei in the sample, and cause them to split

What is a beneficial aspect 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

This is an example of ---

• Radioactive Decay
• Nuclear Fission
• Nuclear Fusion
• Fossil fuel reaction
