Question

Which of the following statements about the interstitial compounds is incorrect ? (A) They have higher melting points than the pure metal (B) They retain metallic conductivity (C) They are chemically reactive (D) They are much harder than the pure metal

Tardigrade Admin · Accepted Answer

Interstitial compounds are obtained when small atoms like H, B, C, N, etc., fit into the interstitial space of lattice metals. These retain metallic conductivity. These resemble the parent metal in chemical properties (reactivity) but differ in physical properties like hardness, melting point, etc.
