In the given nuclear reaction, the element $X$ is $^{22}_{11}\text{Na} \rightarrow X + e^{+} + v$

In the given nuclear reaction, the element $X$ is $^{22}_{11}\text{Na} \rightarrow X + e^{+} + v$
  1. $Ne_{10}^{23}$
  2. $Ne_{10}^{22}$
  3. $Mg_{12}^{22}$
  4. $Na_{11}^{23}$

Solution

As positron is emitting, it is positive beta decay with equation, 

$X_{z}^{A} \rightarrow Y_{z-1}^{A} + e^{+} + \nu$

Hence, $Na_{11}^{22} \rightarrow Ne_{10}^{22} + e^{+} + \nu$
