1. Given the following set of quantum numbers: 3py -1/2. A chemistry student claims that this represents a peanut-shaped electron. Is she correct?

Answer (Am I correct? If not, how?) : She is correct because 3py is a peanut shape with -1/2 being the spin.

2. A chemistry student claims that there is no difference between an s orbital in the first main energy level and an s orbital in the second main energy level. Is he correct?

Answer (Am I correct? If not, how?) : there is a difference because the s orbital in the second main energy level is greater than the first main energy level.
