Question

In nuclear chain fission reaction, every neutron causing fission results in the production of

• A. $2.5$ times more neutrons
• B. Almost less than the one neutron
• C. Exactly one neutron
• D. None of the above

Answer 1

The correct option is A $2.5$ times more neutrons

Nuclear chain reactions are series of nuclear fissions (splitting of atomic nuclei), each initiated by a neutron produced in a preceding fission. For eg- 2.5 neutrons on the average are released by the fission of each Uranium-235 nucleus that absorbs a low energy neutron.
