Question

An electron uniquely characterized by the specific set of quantum numbers $n=5$, $l=2$, $m_l=-1$, and $m_s=+\frac{1}{2}$ is definitively located within which of the following types of atomic orbitals?

Professor PC Thomas Classes · Answer

(c) : The principal quantum number $n = 5$ directly indicates that the electron resides in the fifth principal electron shell. The azimuthal quantum number $l = 2$ explicitly corresponds to a 'd' subshell (where $l=0$ is s, $l=1$ is p, $l=2$ is d, etc.). Therefore, the orbital is decisively identified as a $5d$ orbital.
