Which of the following radio active elements is used to make nuclear fission reaction ?

Key Points

• Uranium is a heavy metal that is used as a primary fuel in nuclear reactors.
• The isotope Uranium-235 is highly fissile and commonly used in nuclear fission reactions.
• When Uranium-235 absorbs a neutron, it splits into smaller nuclei, releasing a tremendous amount of energy.
• The energy released in the fission process is utilized in nuclear power plants to generate electricity.

Additional Information

• Thorium: Thorium is another radioactive element that can be used as nuclear fuel, but it is not fissile in its natural state. Instead, it needs to be converted into Uranium-233 through a breeding process.
• Barium: Barium is not a radioactive element. It is a product of Uranium-235 fission and is commonly found as a byproduct in nuclear reactions.
• Actinium: Actinium is a radioactive element but is not used in nuclear fission reactions. It is primarily used in research and as a neutron source.
