### Nodal Planes

I am still confused about what nodal planes are. During the lecture, nodal planes were defined to have zero probability of electron density. Does this mean that nodal planes are a region where there would be no electrons found?

Yes, a nodal plane is in a region of zero electron probability meaning the planes are perpendicular to the internuclear axis. For example, the S orbital has no internuclear axis; therefore, it has no nodal planes.

Essentially in a nodal plane no electrons will be found. You should know how many nodal planes there are for each orbital (no nodal planes in s orbital, 1 in p orbital, simplest d orbital has 2, etc.)

A nodal plane is a region with zero probability of electron density (no electrons).

The s orbital is spherical and has no nodal planes
The p orbital has 2 lobes on either side of the nucleus and there is a nodal plane.
The d orbital has nodal planes. 3 shapes have 4 lobes along the xy-yz-zx planes. 1 has electrons along x and y axis. 1 has electrons along z axis and donut in xy plane.

p,d, and f orbitals have a nodal plane, so they have non-symmetric electron density distribution.

I think it’s just where you’ll never find electrons
