Question
A $$3p$$ orbital has :
A.
two non spherical nodes
B.
two spherical nodes
C.
one spherical & one non spherical node
D.
one spherical and two non spherical nodes
Answer :
one spherical & one non spherical node
Solution :
TIPS/Formulae :
$$\eqalign{
& {\text{Total nodes}} = n - l \cr
& {\text{No}}{\text{. of radial nodes}} = n - l - 1 \cr
& {\text{No}}{\text{. of angular nodes}} = l \cr
& {\text{For}}\,3p\,\,{\text{sub - shell,}}\,\,n = 3,\,\,l = 1 \cr
& \therefore \,\,\,{\text{No}}{\text{. of radial nodes}} = n - l - 1 = 3 - 1 - 1 = 1 \cr
& \therefore \,\,\,{\text{No}}{\text{. of angular nodes}} = l = 1 \cr} $$
