Question

Which of the following transition elements exhibits a highly anomalous ground state electronic configuration possessing strictly zero electrons in its outermost s-orbital?

Answer: C

💡 Solution & Explanation

Palladium ($Z=46$) has the unique anomalous configuration $[Kr] 4d^{10} 5s^0$. Both 5s electrons migrate to the 4d subshell to achieve the immense stability of a completely filled $d^{10}$ state.
