Removal of the electron gives a cation (left), whereas addition of an electron gives an anion (right). The hydrogen anion, with its loosely held two-electron cloud, has a larger radius than the neutral atom, which in turn is much larger than the bare proton of the cation.

Hydrogen ions (H+) and hydroxide ions (OH–) are two important ions discussed later in this text as acidic and basic ions respectively. Both of these ions can form compounds that you will see in …

hydrogen ion, strictly, the nucleus of a hydrogen atom separated from its accompanying electron. The hydrogen nucleus is made up of a particle carrying a unit positive electric charge, called a proton. The isolated hydrogen ion, represented by the symbol H +, is therefore customarily used to represent a proton.

The dihydrogen cation or molecular hydrogen ion is a cation (positive ion) with formula . It consists of two hydrogen nuclei (protons), each sharing a single electron. It is the simplest molecular ion. The ion can be formed from the ionization of a neutral hydrogen molecule ( ) by electron impact.

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.

When hydrogen loses its electron, the cations can be formed: Hydron : general name referring to the positive ion of any hydrogen isotope (H + ) Proton : 1 H + (i.e. the cation of protium )

Jul 16, 2023 · Hydrogen bonding of hydronium and hydroxide ions to water molecules accounts rather nicely for the unusually large electrical currents observed for some electrolytes containing H and OH. The case of the hydronium ion is illustrated in Figure \(\PageIndex{2}\).

What is an Hydrogen Ion? A hydrogen ion is the nucleus of a hydrogen atom that has been isolated from its electron. A proton is a molecule with a unit of positive electric energy that makes the hydrogen nucleus. Therefore, the disconnected hydrogen ion, signified by the image H+, is usually used to depict a proton.

Jan 24, 2024 · A cation has more protons than electrons, consequently giving it a net positive charge. For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.

Nov 15, 2019 · Hydride or reduced hydrogen is a hydrogen atom which has an extra electron. This means that it is a negatively charged ion, or anion. That is why Hydride ion (H-) has the minus sign distinguishing it from a regular Hydrogen atom (H+).
