SSC GD 2023 PYQ — Question 36

The Correct answer is option 2 i.e. The nucleus of a heavy atom, when bombarded with low-energy neutrons, can be split apart into lighter nuclei.

• In nuclear fission, the nucleus of a heavy atom, typically an isotope of uranium-235 or plutonium-239, is bombarded with low-energy neutrons.
• This can lead to the nucleus becoming unstable and then splitting into two or more lighter nuclei, along with the release of a significant amount of energy.
• The process of nuclear fission is the principle behind nuclear power generation and is also the basis for the release of energy in nuclear weapons.
