Which of the following sets of quantum numbers is not permissible?
- A.n = 3, l = 2, m = -2, s = +1/2
- B.n = 2, l = 1, m = 0, s = -1/2
- C.n = 1, l = 0, m = 0, s = +1/2
- D.n = 3, l = 3, m = -3, s = +1/2Correct answer
Solution
For any principal quantum number , the azimuthal quantum number can have values from to . When , the maximum value of can be (). Therefore, is not permissible for .
