How would you account for the following? Many of the transition elements are known to form interstitial compounds.

Answer»

In the crystal lattice, transition elements have interstitial vacant space into which small sized nonmetal atoms such as H,B, C, or N are trapped. These compounds are non-stoichiometric, neither typically ionic nor covalent. e.g., TiC, MH, Fe3H etc.
