Mention the type of compounds formed when small atoms like H, C and N

1.	Mention the type of compounds formed when small atoms like H, C and N get trapped inside the crystal lattice of transition metals. Also give physical and chemical characteristics of these compounds.
Answer» Interstitial compounds. Characteristic properties : (i) High melting points, higher than those of pure metals. (ii) Very hard. (iii) Retain metallic conductivity. (iv) Chemically inert.
