Question : Name the particle that is most essential to continue the chain reaction during the fission of uranium
Option 1: Electron
Option 2: Proton
Option 3: Neutron
Option 4: Positron
Correct Answer: Neutron
Solution : The correct option is - neutron
The particle that is most essential to continue the chain reaction during the fission of uranium is the neutron. When a uranium nucleus undergoes fission, it splits into two smaller nuclei, releasing several neutrons in the process. These newly released neutrons can go on to strike other uranium nuclei, causing them to undergo fission as well. This process of one fission event leading to more fission events through the release and capture of neutrons is what sustains a chain reaction in a nuclear reactor or a nuclear bomb. Controlling the number of neutrons and their interactions is critical for harnessing nuclear energy or controlling nuclear explosions.
