Both $(a)$ and $(b)$

Vedclass · Answer

(D) For an electron,the principal quantum number $n = 4$ indicates that the electron is in the fourth principal shell. The magnetic quantum number $m = -2$ is allowed only for orbitals where the azimuthal quantum number $l \ge |m|$. Since $|m| = 2$,the value of $l$ must be at least $2$. For $l = 2$,the orbital is a $d-$ orbital. Thus,the electron is in the fourth shell $(n=4)$ and can be in a $d-$ orbital $(l=2)$. Therefore,both statements $(a)$ and $(b)$ are correct.

Which of the following statements are correct for an electron that has $n = 4$ and $m = -2$?
