For each value of the principal quantum number n, what are the possible values of the electron spin quantum number m_s? (There may be more than one correct choice.) A) 0 B) +1/2 C) -1/2 D) +3/2 E) -3/2

Question

Quizplus · Accepted Answer

The electron spin quantum number mS can have two possible values: +1/2 or -1/2. Therefore, for any value of the principal quantum number n, the possible values of mS are always limited to these two options. Choices D and E are incorrect since they both exceed the maximum allowed value of |mS| = 1/2. Choice A is incorrect since the electron spin quantum number cannot be zero.
