Key Concepts

Ionic Hydrides

Ionic hydrides are formed when hydrogen, acting as a hydride ion (H?), bonds with a highly electropositive metal. This type of bonding is characterized by a complete transfer of electron density from the metal to hydrogen, creating a compound with a predominantly ionic character. These hydrides typically form with alkali and alkaline earth metals and display properties such as high melting points and lattice structures similar to other ionic compounds.

Covalent Hydrides

Covalent hydrides occur when hydrogen forms covalent bonds with nonmetals. In these compounds, the electron pair is shared between hydrogen and the other atom rather than transferred. This results in molecules that are generally neutral, with properties that depend on the specific arrangement of atoms and the nature of the covalent bond. The bond polarity in these compounds can vary based on the difference in electronegativity between hydrogen and the partner atom.

Metallic Hydrides

Metallic hydrides involve hydrogen atoms that are incorporated into a metal lattice, often occupying interstitial sites rather than forming discrete bonds like in ionic or covalent hydrides. These hydrides exhibit non-stoichiometric compositions and complex bonding characteristics that include metallic, ionic, and covalent interactions. Their properties are influenced by the metal’s electron structure and can include high electrical conductivity, variable hydrogen storage capacities, and unique magnetic or structural behaviors.
