Q. An element $M$ has the electron configuration $[ Ar ] 3 d ^{5} 4 s ^{2}$ Which one of its oxide is unlikely to exist

The d-and f-Block Elements

Solution:

In metal carbonyl oxidation state of metal is zero as carbonyl is neutral ligand.

$Mn \to Ar3d ^{5} 4s ^{2}$

$MnO_{4}=+8$

Mn cannot show $+8$ oxidation state.
