Which set of quantum numbers could correspond to a 4f-orbital? A) n = 4, l = 4, m_l = +3 B) n = 4, l = 3, m_l = +4 C) n = 4, l = 3, m_l = -3 D) n = 3, l = 2, m_l = +1 E) n = 3, l = 2, m_l = 0

Quizplus · Accepted Answer

For a 4f-orbital, the principal quantum number (n) must be 4, and the azimuthal (angular momentum) quantum number (l) must be 3 (since l = 0 for s-orbitals, 1 for p-orbitals, 2 for d-orbitals, and 3 for f-orbitals). The magnetic quantum number (ml) can range from -l to +l, making option C correct as it fits these criteria.
