### Nodal Planes

What are nodal planes and how are they relevant to orbital shapes?

Nodal planes denote the areas in which the probability of finding electrons is zero.
Each orbital configuration (s,p,d and f) have different nodal planes.

I recommend looking in the textbook pages 37-38 for a visual. You'll notice the nodal planes divide the lobes of the orbitals and that the nodal planes all cross the nucleus.

Hey! Is there any connection between the location of the nucleus and the nodal plane? Is the nucleus located on the nodal plane, since you cannot find an electron in the nucleus or the nodal plane?

nodal planes are where the probability of finding electrons is zero. they're derived from schrodinger's equation

Nodal planes are the regions where there is zero probability density (zero probability of finding an e-). And for s-orbital there is no nodal plane. For p-orbital there are 1. D-orbital has 2 and f-orbital has 3. And I think you can relate this to the angular momentum quantum number. S has an angular momentum quantum number of 0 therefore there's 0 nodal plane, and etc.

A nodal plane will generally include the position of the nucleus as, like you said, you cannot find an electron in the nucleus

a nodal plane is an area where the probability of finding electrons is zero. S orbitals are the only orbitals that have nodal planes considering how the orbital itself is spherical and doesn't intersect the nucleus in any way
