when would we need to draw the s,p,d, or f orbitals? & why do we need to know the planes?

I believe we don't have to draw the orbitals at all for this class.

For the planes, I would say just know that the s-orbital is the only orbital without any nodal planes since it has a symmetric electron p distribution. All of the other orbitals have nodal planes (areas with 0 probability of electron distribution) that can be located at the atom's nucleus.

We will not need to draw the orbitals. Planes refers to the axes the orbitals can be oriented. This shows how for s we can only have 1 (one orientation for a spherical shape) so one orbital in 2 subshell. While p we have three (xy/xz/yz) so there are 3 orbitals in the p subshell. And the patterns continues with d and f orbitals.

I don't think we need to know the orbital shapes/planes in detail enough to be able to draw them out. I agree with Brian said though - just remember that s orbitals don't have a node while the other orbitals do. That would probably be it though.

We do not need to know the orbital shapes / planes to draw them out. You would only need to know the descriptions of each rather than actual pictures planned out. For s, it contains a spherical shape, while p has two lobes on each side of the nucleus with a nodal plane. The d orbital has 3 with 4 lobes of e- p located n xy-yz-zx planes. Although we are not using f orbitals, it contains more complicated shapes with 7 f orbitals.
One thing that you need to know for certain is that s orbital is the only one that has symmetric e- p distribution.

I believe my TA said that we do not need to be too concerned with drawing the different orbitals, but I am still familiarizing myself with them just in case.
