What is the value of the spin quantum number for an electron in a 3d orbital?
A) 3 
B) 2 
C) either or

Quizplus · Accepted Answer

The spin quantum number can have a value of either +1/2 or -1/2. It is not related to the principal quantum number (n) or the orbital quantum number (l). Therefore, the answer cannot be A, B, D, or E. Since we do not have any additional information about the electron in the 3d orbital, we cannot determine its spin direction (up or down), so the value of the spin quantum number could be either +1/2 or -1/2, making C the correct choice.
