Account for the following:Transition metals from interstitial compound

1.	Account for the following:Transition metals from interstitial compounds.Transition metals and their compounds acts as good catalyst.Mn (II) ions shows maximum paramagnetic behaviour amongst the bivalent ions of 3d-series.
Answer» Due to suitable size of interstitial spaces they accomodate smaller atoms and form strong metal-metal bond and that is why transition metals form interstitial compounds. Transition metal shows variable oxidation state and have high charge density on metal ions, hence transition metals and their compounds acts as good catalyst. Mn (atomic no → 25) → [Ar] 3d⁴ 4s² In Mn2+ ions, Mn has the electronic configuration → [Ar]3d⁵ It means there are five impaired electrons, hence it shows maximum paramagnetism.
