Question

Nuclear fission of $^{235}U$ is a chain process. Justify.

✓

Answer

Nuclear fission of $^{235}U$ occurs when nucleus absorbs neutron. When a uranium nucleus absorbs neutron, it breaks into two lighter fragments and releases energy (heat), more neutrons, and other radiation.
When one uranium $235$ nucleus undergoes fission, three neutrons are emitted.
These neutrons emitted in fission cause more fission of the uranium nuclei which yield more neutrons. These neutrons again bring forth fission producing further neutrons.
The process continues indefinitely leading to chain reaction which continues even after the removal of bombarding neutrons.
