how many nodal palnes are there for 4s orbital
Hello,
None.
S Orbital have no nodal Planes Because,
There are no angular nodes in spherical orbitals
Any s orbital has an angular momentum quantum number l Of 0
It has spherical shell nodes known as radial nodes
They are lighter regions of orbital probability densities and where electrons cannot exist
The number of angular nodes are given by l
It can be
- Nodal planes
- In the case of dz^2 or fz^3 , conical nodes
Since l=0 for any s orbital, there are zero nodal planes in 4 s orbital
The ns orbital has (n-1) radial nodes, hence 4s Orbital has (4-1) = 3 radial nodes
Therefore, 4s orbital has no nodal Planes and has 3 nodes
Hope it helps
