hydrideiona
A hydride ion is a diatomic molecule consisting of one hydrogen atom and one electron. It is a negatively charged ion, represented by the chemical formula H-. The hydrogen atom in a hydride ion has gained an extra electron, giving it a total of two electrons in its valence shell. This configuration makes the hydride ion isoelectronic with the noble gas helium. Hydride ions are not typically found in isolation in nature. They are highly reactive species and are generally formed in chemical reactions where a hydrogen atom accepts an electron.
Hydrides are compounds that contain hydrogen, and some of these compounds can be classified as ionic hydrides.
In contrast, covalent hydrides involve hydrogen atoms bonded to other atoms through covalent bonds, where the
