In the given nuclear reaction, the element $X$ is $^{22}_{11}\text{Na} \rightarrow X + e^{+} + v$
- $Ne_{10}^{23}$
- $Ne_{10}^{22}$
- $Mg_{12}^{22}$
- $Na_{11}^{23}$
Solution
As positron is emitting, it is positive beta decay with equation,
$X_{z}^{A} \rightarrow Y_{z-1}^{A} + e^{+} + \nu$
Hence, $Na_{11}^{22} \rightarrow Ne_{10}^{22} + e^{+} + \nu$
