Hydrogen anion

September 18, 2025 - 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 ...

July 28, 2025 - Hydrogen anions are formed when additional electrons are acquired: Hydride: general name referring to the negative ion of any hydrogen isotope (H−)

Hydron: general name referring to the positive ion of any hydrogen isotope (H+) ... In addition, the ions produced by the reaction of these cations with water as well as their hydrates are called hydrogen ions: ... The latter two play an important role in proton hopping according to the Grotthuss mechanism. In connection with acids, hydrogen ions typically refer to hydrons. Hydrogen anions are formed when additional electrons are acquired:

That is why Hydride ion (H-) has the minus sign distinguishing it from a regular Hydrogen atom (H). The two dots after the H means that this ion has two electrons instead of just one.

July 20, 1998 - The formula H+·H2O is also commonly written as H3O+ and denotes the hydronium or oxonium ion. The amount of hydrogen ion present in a water solution is used as a measure of the acidity of a substance; the higher the concentration of hydrogen ...

Answer (1 of 3): When you wrote “hydrogen”, just by itself, you are writing about hydrogen as it is found in nature. That is, a colourless gas, that has a boling point of and so on and so on, and which is made up of hydrogen molecules which have the formula H2.

The meaning of HYDROGEN ION is the cation H+ of acids consisting of a hydrogen atom whose electron has been transferred to the anion of the acid.

The hydrogen anion, the Hydride ion H-, is an extremely strong base so it would be neutralized by the weakest of acids.

3 weeks ago - In chemistry, a hydride is formally the anion of hydrogen (H−), a hydrogen ion with two electrons. In modern usage, this is typically only used for ionic bonds, but it is sometimes (and has been more frequently in the past) applied to all ...

Even amongst my science/astronomy friends, nobody mentioned what I think of as the coolest factoid about Hydrogen (but granted, I’m a nerdy astronomy student and I only asked for one factoid). It’s especially important to the understanding of stars and what we see when we look at the sun! I’m talking of course about the Hydrogen anion (H-).

August 11, 2020 - hydro-. followed by the base name of the anion, followed by the suffix ... Formula for naming acids: Hydro- and Base name of nonmetal and -ic + acid. Example: HCl is hydrochloric acid.

A hydrogen atom that has gained or lost an electron, and thus has an electric charge. The positive hydrogen ion, H+, has lost its only electron and therefore consists of a single proton. A nebula containing H+ ions is known as an H II region. The negative hydrogen ion, H−, has gained a second ...

The anion is probably easier to explain, being just an H atom with an extra electron added. This is the hydride ion, and occurs in some of the hydrides of the most electropositive m...

July 23, 2025 - Thus, hydride (hydrogen anion) has a negative charge. In hydride, the oxidation number of hydrogen is -1.

WE are all so much entertained by Prof. H. E. Armstrong's broadside attacks that those of us who happen to come within his range must not complain; but I feel that I must protest against his criticism (NATURE, April 17, p. 553) of the beautiful experiment of Bardwell which proved that hydrogen is an anion in metallic hydrides (J. Am.
