alleryMagnetic quantum number m_l for a 3d orbital can be:
AOnly positive
B-2 to 0
C0 to 2
D-2, -1, 0, +1, +2 (five values)
Answer & Solution
Correct answer: D. -2, -1, 0, +1, +2 (five values)
For d-orbital (l = 2): m_l takes values -l to +l = -2, -1, 0, +1, +2 (five values).
Hence 5 d-orbitals.
With Pauli (each holds 2 e⁻): total 10 electrons in d-subshell.
