Nuclear Fission: The Power and Dangers of Splitting Atoms

What is the primary element used in nuclear fission reactions?

• Carbon

• Uranium

• Hydrogen

• Helium

In a typical nuclear fission reaction, what happens to the uranium nucleus after absorbing a neutron?

• It becomes stable

• It splits into smaller fragments

• It releases helium

• It remains unchanged

What is the result of the mass difference in a nuclear fission reaction?

• It remains as mass

• It is lost as sound

• It is converted into energy

• It is absorbed by the environment

What is used in a controlled fission process to limit the number of free neutrons?

• Neutron absorbing materials

• Lead rods

• Graphite

• Water

What is the main application of uncontrolled nuclear fission?

• Space exploration

• Medical imaging

• Fueling nuclear bombs

• Generating electricity
