Vedclass · Answer

(B) The distance of an electron from the nucleus depends on the principal quantum number $n$. In the configuration $4s^2 3d^{10}$,the outermost electrons are in the $n=4$ shell. In the configuration $4s^0 3d^{10}$,the outermost electrons are in the $n=3$ shell. Since $n=3 < n=4$,the electrons in the $3d^{10}$ configuration are closer to the nucleus compared to those in the $4s^2 3d^{10}$ configuration.

Which of the following electronic configurations is closer to the nucleus: $4s^2 3d^{10}$ or $4s^0 3d^{10}$?
