How Many Radial Nodes Are Present In $3d$ Orbital?

The radial nodes in $3\mathrm{d}$ orbital is explained below:

Step 1:

Number of radial nodes $=\mathrm{n}-\mathrm{l}-1$ , where $\mathrm{n}=$Principal quantum number, $\mathrm{l}=$azimuthal quantum number

Step 2:

For $3\mathrm{d}$ orbital, $$\begin{gathered} \mathrm{n}=3 \\ \mathrm{l}=2 \end{gathered}$$

Step 3:

Hence no. of radial nodes for $3\mathrm{d}$ orbital, $$\begin{gathered} =3-2-1 \\ =0 \end{gathered}$$

Therefore, above points clearly explain and evaluate the no. of radial nodes in $3\mathrm{d}$ orbital.
