Formed when hydrogen reacts with highly reactive alkali metals (Group 1) or alkaline earth metals (Group 2, like Calcium).
Formed when hydrogen bonds with non-metals (Groups 13–17). hydride
These are crystalline, high-melting-point solids. Formed when hydrogen reacts with highly reactive alkali
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 hydride
Formed by many transition metals (d-block and f-block elements).
