Question

how many nodal planes are there in atomic orbitals for the principal quantum number n=3 ?

Answer 1

2 nodal plane will be there

Answer 2

Answer:

Explanation:

Shell with n=3 has 3s,3p and 3d

s has no nodal plane

Each px,py,pz has 1 so total 3

dz2 has no nodal plane and

dxy,dyz,dzx,dx2-y2 has 2 each so total 8

All total=8+3+0=11

Hence answer is 11.
