Question

Transition elements extensively form stable, non-stoichiometric interstitial compounds with lightweight elements. Which of the following characteristics accurately and comprehensively define these specific compounds?

Prashant Kotian · Accepted Answer

Correct answer: A,C,D. Interstitial compounds trap small atoms () in the metallic lattice without forming proper covalent bonds, so the delocalized electron "sea" remains undisturbed, retaining metallic conductivity. Physically, the trapped atoms severely restrict the sliding of crystal planes, making the compounds incredibly hard, raising their melting points above the pure metal, and rendering them highly chemically inert.
