Q10: What are metallic/interstitial hydrides? How do they differ from molecular hydrides?
Answer: A hydride is a binary chemical that contains an element and a hydrogen atom. Metallic hydrides are also known as interstitial hydrides. Metallic/interstitial hydrides are compounds in which transition metals and hydrogen are bonded together. They are the source of many d-Block and f-Block elements. Heat and electricity conductors, these hydrides are. Molecular hydrides are hydrides that have additional electronegative atoms linked to the H-atom. The electrical conductivity of metallic hydrides is strong, while that of molecular hydrides is low. Metallic hydrides are solid, whereas molecular hydrides are gaseous. Interstitial or metallic hydrides are formed when hydrogen and transition metals bind, as opposed to molecular hydrides, which contain bonding between an electronegative atom and hydrogen.
