In the given nuclear reaction, the element X is ₁₁²²Na → X + e⁺ + ν (a) ₁₁²³Na (b) ₁₀²³Ne (c) ₁₀²²Ne (d) ₁₂²²Mg

Answer: (c). β⁺ decay: A unchanged, Z decreases by 1 ( e⁺ and ν carry the charge and lepton number). A = 22, Z = 11 - 1 = 10, which is neon. So the answer is (c) ₁₀²²Ne.

Nuclear Reactions & Q-value

In the given nuclear reaction, the element X is

${}_{11}^{22}Na \rightarrow X + e^{+} + \nu$

Show answer and solution

Answer: (c)

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