$3d^5\, 4s^2$

Vedclass · Answer

(A) The element with the outer electron configuration $3d^5\, 4s^2$ is Manganese $(Mn)$.This configuration corresponds to the $3d$ transition series.$Mn$ has $7$ valence electrons ($5$ in $d$-orbital and $2$ in $s$-orbital),allowing it to exhibit a wide range of oxidation states from $+2$ to $+7$ in its compounds.This is the largest number of oxidation states among the given options.

The element with which of the following outer electron configuration may exhibit the largest number of oxidation states in its compounds?
