हिन्दीIn the given nuclear reaction, the element X is: \( ^{22}_{11}\text{Na} \rightarrow \text{X} + \text{e}^+ + \nu \)
Correct answer · Option 1
\( ^{22}_{10}\text{Ne} \)
Explanation
In positron emission (\( \text{e}^+ \)), atomic number decreases by 1 while mass number remains unchanged. Thus, \( ^{22}_{11}\text{Na} \rightarrow \,^{22}_{10}\text{Ne} + \text{e}^+ + \nu \).
