As per your syllabus, the magnetic quantum number m_l takes how many values for a given azimuthal quantum number l?
AAlways 2 values
BAlways 1 value
C(2l + 1) values, ranging from −l through 0 to +l
Dl values
Answer & Solution
Correct answer: C. (2l + 1) values, ranging from −l through 0 to +l
As per your syllabus, m_l = −l, −(l−1), … 0, …, +l — total 2l + 1 values, giving the orientations of orbitals in each subshell.
