E)only +1/2.

Question

Quizplus · Accepted Answer

The electron spin quantum number can have two possible values, which are -1/2 and +1/2. This is because electrons can only have two possible spin orientations, which are "spin up" and "spin down". The spin up orientation corresponds to +1/2, while the spin down orientation corresponds to -1/2. Therefore, choice D is the best answer, as it contains both possible values for the electron spin quantum number.
