P) The d-orbital which has two angular nodes	$3{\mathrm{d}}_{{\mathrm{x}}^2-{\mathrm{y}}^2}$
Q) The d-orbital with two nodal surfaces formed cones	$3{\mathrm{d}}_{{\mathrm{z}}^2}$
R) The orbital without angular node	$4\mathrm{f}$
S) The orbital which has three angular nodes	$3\mathrm{s}$

 

Nodal planes =l Angular nodes 

For $3{\mathrm{d}}_{{\mathrm{x}}^2-{\mathrm{y}}^2}$, number of angular nodes = 2 $\left(\because \mathrm{for} \mathrm{d} \mathrm{orbital}, \mathrm{l}=2\right)$

$\mathrm{For} 3{\mathrm{d}}_{{\mathrm{z}}^2}$, number of nodal surfaces forming cones=2

The $3{\mathrm{d}}_{{\mathrm{z}}^2}$ orbital has two nodal cones whose tips meet at the nucleus, which separate the “dumbbell” lobes from the “doughnut” ring.

For 3s orbital, number of angular nodes=0$\left(\because \mathrm{for} \mathrm{s}-\mathrm{orbital}, \mathrm{l}=0\right)$

For 4f orbital, number of angular nodes = 3$\left(\because \mathrm{l}=3 \mathrm{for} \mathrm{f}-\mathrm{orbital}\right)$
