Vedclass · Answer

(D) Among the isotopes of hydrogen,tritium ($^{3}H$ or $T$) is radioactive in nature. It undergoes $\beta^{-}$-decay to form helium-$3$ $(^{3}He)$. The reaction is: $^{3}_{1}H \rightarrow ^{3}_{2}He + ^{0}_{-1}e$. The half-life $(t_{1/2})$ of tritium is approximately $12.33 \ years$,which satisfies the condition of being $> 12 \ years$.

Isotope$(s)$ of hydrogen which emits low energy $\beta^{-}$ particle with $t_{1/2}$ value $> 12 \ years$ is/are :
