2. The chemical properties of the interstitial compounds are the same as those of the parent transition metals.
3. Their densities are less than that of the parent metal.
4. Their melting points are higher than those of the pure metals.
5. Interstitial substances are very hard. Certain borides have a hardness that is similar to diamond.
6. They are chemically inert.
