Question:
Which of the following forms of hydrogen emits low energy $\beta^{-}$particles?
Correct Option: , 2
Solution:
For tritium $\left({ }_{1}^{3} H\right)$
No. of neutron $(\mathrm{n})=2$
No. of proton $(\mathrm{p})=1$
$\frac{n}{p}=2$
$\because \frac{\mathrm{n}}{\mathrm{p}}$ is high
tritium wil emit $\beta$ particle.
