Question

Write any four properties of interstitial compounds.

Mention two important properties of interstitial compounds.

Answer 1

1. They are hard and good conductors of heat and electricity.
2. Their chemical properties are similar to the parent metal.
3. Their melting points are higher than the pure metals.
4. Their densities are less than the parent metal.

Answer 2

1. These compounds have higher melting points than those of pure metals.
2. Interstitial substances are very hard. Certain borides have a hardness that is similar to diamond.
3. They exhibit conductivity similar to that of the pure metal.
4. They are chemically inert.
