The number of spherical nodes in $$3p$$ -orbital is/are
A.
one
B.
three
C.
two
D.
None of these
Answer :
one
Solution :
The number of spherical nodes in any orbital $$\left( { = n - l - 1} \right)$$
For $$3p$$ -orbital, $$n = 3$$ and $$l = 1$$
∴ Number of spherical nodes
$$\eqalign{
& = n - l - 1 \cr
& = 3 - 1 - 1 \cr
& = 3 - 2 \cr
& = 1\,node \cr} $$
