Vedclass · Answer

(C) Interstitial hydrides are formed by the absorption of hydrogen into the metal lattice. These hydrides are non-stoichiometric,meaning their composition varies with temperature and pressure. They are generally less dense than the parent metal because the crystal lattice expands upon the inclusion of hydrogen atoms. Not all $d-$ block metals form these hydrides; metals of groups $7, 8,$ and $9$ do not form them,which is known as the hydride gap.
