Mention the type of compounds formed when small atoms like H, C and N gettrapped inside the crystal lattice of transition metals. Also give physical and chemical characteristics of these compounds.
Compounds formed when small atoms like H,C and N get trapped inside the crystal lattice of transition metals are called interstitial compounds.
Some properties of interstitial compounds are called:
5) Compounds are very hard
6) They are chemically inert
7) Have high melting points, higher than pure metals
8) They retain metallic conductivity.
