What are metallic/interstitial hydrides? How do they differ from molecular hydrides?
Answers (1)
Metallic hydrides are usually formed by d and f block elements. These hydrides are good conductors of heat and electricity; they lack Hydrogen, which makes them non-stoichiometric. These differ from molecular hydrides as they are formed by s, p block elements while the metals of group 7, 8, 9 do not form hydrides. Molecular hydrides are not good conductors of electricity or heat, unlike the metallic hydrides. They are also volatile compounds which have low melting and boiling points, but metallic hydrides, on the other hand, are hard in texture and have a certain metallic lustre.
