$[MnO_4]^-$

Vedclass · Answer

(A) The complex ion $[MnO_4]^-$ has no $d$-electron in the central metal atom.The electronic configuration of $Mn$ is $[Ar] 3d^5 4s^2$. In $[MnO_4]^-$,the oxidation number of $Mn$ is $+7$,meaning all the $3d$ and $4s$ electrons are lost to form the $[MnO_4]^-$ complex.Thus,the electronic configuration of $Mn(VII)$ is $[Ar] 3d^0 4s^0$,confirming it has no $d$-electrons.In contrast,the central metal atoms in $[Co(NH_3)_6]^{3+}$,$[Fe(CN)_6]^{3-}$,and $[Cr(H_2O)_6]^{3+}$ have $6$,$5$,and $3$ $d$-electrons respectively.
