हिन्दीFor hydrogen-like species containing only one electron, the radius of the \( n^{\text{th}} \) orbit is proportional to:
Correct answer · Option 4
\( \frac{n^2}{Z} \)
Explanation
The radius expression for hydrogen-like species is \( r_n = \frac{52.9 n^2}{Z} \text{ pm} \), so it is proportional to \( \frac{n^2}{Z} \).
