Vedclass · Answer

(D) The $3d$ transition series corresponds to elements where the $3d$ orbital is being filled, which are elements with atomic numbers $21$ to $30$.Electronic configuration of $Cr$ $(Z=24)$ is $[Ar] 3d^5 4s^1$.Electronic configuration of $Cu$ $(Z=29)$ is $[Ar] 3d^{10} 4s^1$.Both elements have an $ns^1$ (specifically $4s^1$) configuration and belong to the $3d$ transition series.Therefore, the correct answer is $24$ and $29$.

What is the atomic number of an element having $ns^1$ electronic configuration and belonging to the $3d$ transition series?
