Correct Answer is : P→4,Q→3,R→2,S→1P arrow 4, Q arrow 3, R arrow 2, S arrow 1P→4,Q→3,R→2,S→1

List-I	List-II
(P) ${}^{238}_{92}\mathrm{U} \rightarrow {}^{234}_{91}\mathrm{Pa}$	(1) one $\alpha$ particle and one $\beta^{+}$ particle
(Q) ${}^{214}_{82}\mathrm{Pb} \rightarrow {}^{210}_{82}\mathrm{Pb}$	(2) three $\beta^{-}$ particles and one $\alpha$ particle
(R) ${}^{210}_{81}\mathrm{TI} \rightarrow {}^{206}_{82}\mathrm{Pb}$	(3) two $\beta^{-}$ particles and one $\alpha$ particle
(S) ${}^{228}_{91}\mathrm{Pa} \rightarrow {}^{224}_{88}\mathrm{Ra}$	(4) one $\alpha$ particle and one $\beta^{-}$ particle
	(5) one $\alpha$ particle and two $\beta^{+}$ particles
