Q.Explain the meaning of angular node. As well.as how angular node of 3dz2 is zero thoudh l for d =2
15. A : The number of angular nodes in is zero.
R : Number of angular nodes of atomic orbitals is equal to value of l.
Dear student,
Angular node is a plane passing through the nucleus.
The radial node for 3dz2 is 0 since
radial node = n-l-1
n = 3, l = 2 , so radial node = 3-2-1 = 0
Angular node = l
So for 3dz2 , angular node should be 2 but it is not so. Due to the 3d structure of dz2 orbital i.e dumble in xz plane and ring in y x plane makes the no of nodal plane to be zero.
