Hydrogen anion - Wikipedia
The hydrogen anion, H −, is a negative ion of hydrogen, that is, a hydrogen atom that has captured an extra electron. The hydrogen anion is an important constituent of the atmosphere of stars, such as the Sun. In chemistry, this ion is called hydride. The ion has two electrons bound by the electromagnetic force to a nucleus containing one proton.
Hydride - Wikipedia
In chemistry, a hydride is formally the anion of hydrogen (H −), a hydrogen atom with two electrons. [1] In modern usage, this is typically only used for ionic bonds, but it is sometimes (and more frequently in the past) been applied to all compounds containing covalently bound H atoms.
The Hydride Anion in an Extended Transition Metal Oxide Array …
2002年3月8日 · We present the synthesis and structural characterization of a transition metal oxide hydride, LaSrCoO 3 H 0.7, which adopts an unprecedented structure in which oxide chains are bridged by hydride anions to form a two-dimensional extended network.
Hydride | H- | CID 166653 - PubChem
2021年10月14日 · Hydride is the general name for the hydrogen anion H (-), to be used without regard to the hydrogen nuclear mass (either for hydrogen in its natural abundance or where it is not desired to distinguish between the isotopes). Metal hydrides are either liquids or solids shipped within a solution.
Hydrides - Chemistry LibreTexts
2023年6月30日 · Hydrides are classified into three major groups, depending on what elements the hydrogen bonds to. The three major groups are covalent, ionic, and metallic hydrides. Formally, hydride is known as the negative ion of a hydrogen, H -, also called a hydride ion. Because of this negative charge, hydrides have reducing, or basic properties.
Hydride | Properties, Reactions & Uses | Britannica
Structural studies show that these compounds contain a hydride anion, H −, with a crystallographic radius that is dependent on the identity of the metal but intermediate to that of the fluoride ion, F − (1.33 angstroms), and the chloride ion, Cl − (1.84 angstroms).
Expanding frontiers in materials chemistry and physics with …
2018年2月22日 · The hydride anion is strongly reductive in nature, with a large standard redox potential of −2.2 V (H − /H 2 vs. SHE), so a transition metal oxyhydride appears impossible to stabilize.
6.4: Boron Hydrides - Chemistry LibreTexts
The borohydride anion (or more properly the tetrahydridoborate anion), BH 4-, can be considered as the Lewis acid-base complex between borane and H-. A typical synthesis involves the reaction of a borate ester with a hydride source, (6.4.9).
Hydride Anion Substitution Boosts Thermoelectric Performance …
2023年4月18日 · Here we propose a new approach to reduce κ lat with keeping high σ and demonstrate ZT enhancement in polycrystalline SrTiO 3 by hydrogen anion (H −) substitution at the oxygen ion (O 2−) sites (i.e., SrTiO 3− x H x).
Chapter 1: Chemistry of Mixed-anion Compounds - Royal Society …
2024年3月28日 · Hydride anion (H −) is a unique anionic species that differs from conventional p-block anions. Hydrogen, consisting of one proton and one electron, is the simplest atom and is located at the top left corner (s-block) of the periodic table.
