Which set of quantum numbers describes an electron in a 3d subshell orbital?
Answer and explanation
Correct answer: A. n = 3, l = 2, ml = -1, ms = +1/2 pathway
For a 3d subshell, the principal quantum number n is 3 and the azimuthal (angular momentum) quantum number l is 2 (s=0, p=1, d=2, f=3). Magnetic quantum number ml can take integer values from -2 to +2, and ms is +/-1/2.
