$Ag$

Vedclass · Answer

(B) The electronic configuration of the given elements are:$Dy$ $(Z=66)$: $[Xe] 4f^{10} 6s^2$. The last electron enters the $4f$ orbital.$Ag$ $(Z=47)$: $[Kr] 4d^{10} 5s^1$. The last electron enters the $4d$ orbital,which is $(n-1)d$ where $n=5$.$Pu$ $(Z=94)$: $[Rn] 5f^6 7s^2$. The last electron enters the $5f$ orbital.$Pa$ $(Z=91)$: $[Rn] 5f^2 6d^1 7s^2$. The last electron enters the $5f$ orbital.Therefore,$Ag$ is the element where the last electron is placed in the $(n-1)d$ orbital.

Identify the element from the following such that the last electron is placed in the $(n-1)d$ orbital.
