Which of the following is NOT a physical or chemical characteristics of interstitial compounds?
- A They have high melting points, higher than those of pure metals.
- B They are very soft and ionic in nature.
- C They retain metallic conductivity.
- D They are chemically inert and usually non-stoichiometric.
Answer & Solution
Correct Answer
(B) They are very soft and ionic in nature.
Step-by-step Solution
Detailed explanation
Interstitial compounds are formed when small atoms like H, C, or N are trapped inside the crystal lattices of transition metals. The principal physical and chemical characteristics of interstitial compounds are: (i) They have high melting points, higher than those of pure…
