Vedclass · Answer

(A) The maximum oxidation state of an element is generally related to the number of valence electrons.For $Mn$ ($Z=25$,configuration: $[Ar] 3d^5 4s^2$),the maximum oxidation state is $+7$.For $Cl$ ($Z=17$,configuration: $[Ne] 3s^2 3p^5$),the maximum oxidation state is $+7$ (e.g.,in $HClO_4$).For $Cr$ $(Z=24)$,the maximum oxidation state is $+6$.For $V$ $(Z=23)$,the maximum oxidation state is $+5$.For $S$ $(Z=16)$,the maximum oxidation state is $+6$.Therefore,the pair showing the highest oxidation state of $+7$ is $Mn$ and $Cl$.

Which among the following pairs of elements show the highest oxidation state of $+7$ in their different compounds? (Atomic numbers: $Cr=24, V=23, Mn=25, Cl=17, S=16$)
