Interstitial compounds are formed when small atoms are trapped inside the crystal lattice of metals. Which of the following is not the characteristic property of interstitial compounds?

Question

Philoid · Accepted Answer

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:

1) Compounds are very hard

2) They are chemically inert

3) Have high melting points, higher than pure metals

4) They retain metallic conductivity.

So, interstitial compounds are actually chemically inert.
