Vedclass · Answer

(D) transition element is defined as an element which has an incompletely filled $d$-orbital in its ground state or in any of its oxidation states.$Zn$ $([Ar] 3d^{10} 4s^2)$,$Cd$ $([Kr] 4d^{10} 5s^2)$,and $Hg$ $([Xe] 4f^{14} 5d^{10} 6s^2)$ have completely filled $d$-orbitals in their ground state as well as in their common oxidation states $(+2)$.$Cu$ $([Ar] 3d^{10} 4s^1)$ has a completely filled $d$-orbital in its ground state,but in its $+2$ oxidation state $(Cu^{2+})$,it has a $3d^9$ configuration,which is incompletely filled.Therefore,$Cu$ is considered a transition element.
