We have two radioactive nuclei A and B. Both convert into a stable nucleus C. Nucleus A converts into C after emitting two α-particles and three β-particles. Nucleus B converts into C after emitting one α-particle and five β-particles. At time t = 0, nuclei of A are 4No and that of B are No. Half life of A (into the conversion of C) is 1 min and that of B is 2 min. Initially number of nuclei of C are zero.
If atomic numbers and mass numbers of A and B are Z1, Z2 ,A1 and, A2, respectively. Then,
(a) Z1 - Z2 = 6
(b) A1 - A2 = 4
(c) Both (a) and (b) are correct
(d) Both (a) and (b) are wrong
