They are generally grouped into three categories based on the type of chemical bond involved: 1. Ionic (Saline) Hydrides
), in many hydrides, it acts as the more electronegative partner, sometimes even forming a negative anion ( H−cap H raised to the negative power hydride
Formed when hydrogen bonds with non-metals (Groups 13–17). They are generally grouped into three categories based
Formed by many transition metals (d-block and f-block elements). in many hydrides
When they react with water, they release hydrogen gas and form a base. Example: Sodium hydride ( NaHcap N a cap H ), often used in organic chemistry as a powerful base. 2. Covalent (Molecular) Hydrides
These are crystalline, high-melting-point solids.
These are mostly gases or volatile liquids held together by shared electrons. Sub-types:
