Question

_________ isotope is the source of nuclear energy.

Answer 1

Radioactive isotopes:

1. Radioactive isotopes are chemical elements that have unstable nuclei and dissipate excess energy by spontaneously emitting radiations.
2. Radioactive isotopes are used for various purposes.
3. Uranium-235 is used as a fuel in nuclear power plants for generating electricity.
4. When the heavy nuclei of uranium-235 atoms are bombarded with slow-moving neutrons, it breaks up into smaller nuclei with the release of a tremendous amount of heat energy.
5. The heat energy is used to boil water in a boiler to form steam.
6. The steam runs turbines to run generators to generate electricity.

Hence, the Uranium-235 isotope is the source of nuclear energy.
