JEE Physics Practice Question

List-I shows different radioactive decay processes and List-II provides possible emitted particles. Match each entry in List-I with an appropriate entry from List-II, and choose the correct option. List-I (P) ${ }_{92}^{238} U \rightarrow{ }_{91}^{234} \mathrm{~Pa}$ (Q) ${ }_{82}^{214} \mathrm{~Pb} \rightarrow{ }_{82}^{210} \mathrm{~Pb}$ (R) ${ }_{81}^{210} \mathrm{Tl} \rightarrow{ }_{82}^{206} \mathrm{~Pb}$ (S) ${ }_{91}^{228} \mathrm{~Pa} \rightarrow{ }_{88}^{224} \mathrm{Ra}$ List-II (1) one $\alpha$ particle and one $\beta^{+}$particle (2) three $\beta^{-}$particles and one $\alpha$ particle (3) two $\beta^{-}$particles and one $\alpha$ particle (4) one $\alpha$ particle and one $\beta^{-}$particle (5) one $\alpha$ particle and two $\beta^{+}$particles
