@surry99 would you happen to be able to help me with this question?

OpenStudy (surry99):

Principal energy levels are identified by numbers starting at 1, 2, 3 etc. So the answer is 2.

OpenStudy (surry99):

px identifies a particular orbital shape and orientation + 1/2 refers to the spin on an electron s refers to any spherical orbital
