In all how many nodal planes are there in the atomic orbitals for the principal quantum number n = 3
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
In n = 3 shell
1s (3s)
3p (Px, py, pz)
5d (dxy, dyz, dxz, 
, 
)
* S has no nodal plane.
* Each of Px, py, pz has one nodal plane, which means a total of three nodal planes.
* 
has no nodal plane and each of dxy, dxz, dyz, 
has two nodal planes which means a total of eight nodal planes.
Hence n = 3, a total of 11 nodal planes are there.
