Question:
The plots of radial distribution functions for various orbitals of hydrogen atom against ' $r$ ' are given below:
The correct plot for $3 \mathrm{~s}$ orbital is:
Correct Option: 1
Solution:
$3 s$ orbital
Number of radial nodes $=\mathrm{n}-\ell-1$
For $3 \mathrm{~s}$ orbital $n=3 \quad \ell=0$
Number of radial nodes $=3-0-1=2$ It is correctly represented in graph of option $\mathrm{D}$
