What are the nodal planes of the dx2y2 orbital?

1 Answer

The nodal planes of the dx2y2 orbitals are the non-axial planes.

Explanation:

A nodal plane or nodal surface of a wave-function is an area where there is zero displacement; zero electron density.

Example: 3dx2y2 orbital

Since the dorbitals have definite geometric properties, it is easy to recognize such planes/surfaces, and these are the regions which have no axial component in the xy plane.
