Concept Introduction:
The compound containing hydrogen and just one other element called binary hydride. Type of hydride formed depends upon the element present in the group. Types of binary compounds are, ionic hydride, metallic hydride and covalent hydride.
Ionic hydride: Ionic hydrides are formed by alkali metals and heavier alkaline earth metals. Thus, the bond between alkali metal and hydrogen is known as ionic bond.
Covalent hydride: Covalent hydrides are formed by non-metals. The compound contains hydrogen which is bonded to another element by covalent bond. Most of the covalent hydrides consists of separate, small molecule have relatively weak intermolecular force of attraction, so they are gas or volatile liquid at normal temperature.
Metallic hydride: Metallic hydrides are formed by

Metallic hydride: Metallic hydrides are formed by transition metals, lanthanide and actinide metals in which hydrogen will be present in variable amount. This type of bond is known as metallic bond.
