Question
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?
Options
They have high melting points in comparison to pure metals.
They are very hard.
They retain metallic conductivity.
They are chemically very reactive.
Solution
They are chemically very reactive.
Explanation:
Interstitial compounds/alloys are substances that are formed when a small atom like carbon, hydrogen, boron, nitrogen can occupy space in their lattices. All the properties mentioned above are true for interstitial compounds except, they are chemically inert.
