What do we need to know in regards to orbitals for the upcoming test? I'm pretty sure my TA told me that orbitals weren't going to be on the test, but then Lavelle went over them on Friday and said that they would be on the test.
I believe that everything that was covered up till this Friday's lecture is going to be on the test. So basically we need to know the 4 quantum numbers and which combination of quantum numbers is valid. I would look at the diagram with boxes that visualize the shells and subshells. I would also know the shape of the atomic orbitals and which ones are better at shield. (These were all questions from the homework.
According to my TA and what I remember from Lavelle, we will only need to know what quantum numbers each orbital is represented by. We will not need to draw any and we don't even need to know the orientation (only that a particular quantum number means a particular orientation). Really just focus on the numbers not the shapes.

This just means that these are the nodal planes, or where there is no electron density.
