Vedclass · Answer

(B) $1$. The general electronic configuration of transition elements is $(n-1)d^{1-10} ns^{0-2}$.$2$. For the $3d$ series, $n=4$, so the configuration is $[Ar] 3d^{1-10} 4s^{1-2}$.$3$. For the $4d$ series, $n=5$, so the configuration is $[Kr] 4d^{1-10} 5s^{0-2}$.$4$. For the $5d$ series, $n=6$, so the configuration is $[Xe] 4f^{14} 5d^{1-10} 6s^{0-2}$.$5$. Therefore, the configuration $[Kr] 4d^{1-10} 5s^{0-2}$ corresponds to the $4d$ series.

Which of the following series of transition elements has the general electronic configuration $[Kr] 4d^{1-10} 5s^{0-2}$?
