Possible set of quantum numbers for which: and is — Atomic Structure Chemistry Question

💡 Solution & Explanation

The set is partially specified. With $l=3$, the magnetic quantum number $m$ can take values $-3, -2, -1, 0, +1, +2, +3$ (a total of $2l+1 = 7$ values). Since spin is fixed at $+1/2$, there are 7 fully defined sets of quantum numbers possible. Therefore, correct answer is B.
