Nuclear Reactions & Q-value

In the given nuclear reaction, the element X is

1122Na→X+e++ν{}_{11}^{22}Na \rightarrow X + e^{+} + \nu

Show answer and solution

Answer: (c)

  1. β+\beta^+ decay: AA unchanged, ZZ decreases by 1 (e+e^+ and ν\nu carry the charge and lepton number).
  2. A=22A = 22, Z=11−1=10Z = 11 - 1 = 10, which is neon.
  3. So the answer is (c) 1022Ne{}_{10}^{22}\text{Ne}.
