-235 ate d Passage I We have two radioactive nuclei A and B. Both convert into a stable nucleus C. Nucleus A converte into C after emitting two a particles and three - particles. Nucleus B converts into C after emitting one a-particle and five B-particles. A time t = 0. nuclei of A are 4N, and that of B are No. Half-life of A (into the conversion of C) is 1 min and that of Bis 2 min. Initially number of nuclei of Care zero. 23. If atomic numbers and mass numbers of A and B are Z1, Z2, A, and A, respectively. Then : (1) 21 - 22 = 6 (2) A1 - A2 = 4 (3) both (1) and (2) are correct (4) both (1) and (2) are wrong 24. What are number of nuclei of C, when number of nuclei of A and B are equal ? (1) 2N, (2) 3N. (3) (4) 25.
