Which of the following statements about the interstitial compounds is incorrect?
They retain metallic conductivity
They are chemically reactive
They are much harder than the pure metal
They are much harder than the pure metal
B.
They are chemically reactive
Interstitial compounds are obtained when small atoms like H, B, C, resemebleN etc.fit into the lattice etc. fit into the lattice of other elements. These retain metallic conductivity resemble their parent metal in chemical properties (reactivity)but differ in physical properties like hardness, melting point etc.
