What is a nodal plane ? How many nodal plance are possible for 2p and 3d - orbitals ?

Explanation

The probability to find the electron at a point within the uncleus in an atom is negligible . This point is called 'nodal point '.'The plane ' (or 'angular node') . So nodal plane is the plane of zero electron density .
The number of nodal planes for an orbital is equal to its Azimuthal quantum number 1 value .
Thus ,
No of nodal planes for s - orbital (l=1) is zero
No of nodal planes for s - orbital (l=2) is 1.
No of nodal planes for s - orbital (l=0) is 2.
No of nodal planes for s - orbital (l=3) is 3 .
