$^{235}U$ is fissionable by thermal neutrons.

Vedclass · Answer

(A) $^{235}U$ is a fissile isotope,meaning it can undergo nuclear fission when it captures a thermal (slow) neutron. This process releases energy and additional neutrons,which can sustain a chain reaction. In contrast,$^{238}U$ is fertile but not fissile with thermal neutrons; it requires fast neutrons to undergo fission,and even then,it is much less likely to fission compared to $^{235}U$. Spontaneous fission is a rare decay mode for $^{235}U$ compared to alpha decay. Therefore,the statement that $^{235}U$ is fissionable by thermal neutrons is correct.
