Answer :
Final answer:
Uranium-235 undergoes nuclear fission when bombarded with a neutron, releasing energy and causing a chain reaction.
Explanation:
Uranium-235 is commonly used in nuclear power due to its ability to undergo nuclear fission when bombarded with a neutron. During fission, U-235 splits into fission fragments and additional neutrons, releasing energy in the process. This leads to a chain reaction that provides the energy needed to power a nuclear reactor.
