How many electrons can be described by the quantum numbers n = 4, l = 3, m_l = 0? A) 2 B) 10 C) 6 D) 0 E) 14

Question

Quizplus · Accepted Answer

The quantum numbers given describe a specific subshell in an atom. Here, n = 4 defines the energy level, l = 3 indicates the f subshell, and ml = 0 specifies one of the orbitals within that subshell. Since each orbital can hold a maximum of 2 electrons (with opposite spins), only 2 electrons can have this exact set of quantum numbers.
