The helium hydride ion, hydridohelium(1+) ion, or helonium is a cation (positively charged ion) with chemical formula HeH +. It consists of a helium atom bonded to a hydrogen atom, with one electron removed.
The helium hydride ion HeH + has been known since 1925. [70] The protonated dihelium ion He 2 H + can be formed when the dihelium cation reacts with dihydrogen: He + 2 + H 2 → He 2 H + + H. This is believed to be a linear molecule. [70] Larger protonated helium cluster ions exist He n H + with n from 3 to 14. He 6 H + and He 13 H + appear to ...
Whereas the carbon–helium-ion bond breaks spontaneously and immediately to yield a carbocation, bonds of other elements to helium are more stable. For example, molecular tritium T 2 or tritium-hydrogen HT. On decay, these form a stable helium hydride ion [HeH] + (respectively [3 HeT] + or [3 HeH] +), which is stable enough to persist. This ...
The dihydrogen cation or hydrogen molecular ion is a cation (positive ion) with formula +. It consists of two hydrogen nuclei , 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
Structure of the helium hydride ion, HHe + Structure of the suspected fluoroheliate anion, OHeF −. Helium has a valence of zero and is chemically unreactive under all normal conditions. [108] It is an electrical insulator unless ionized.
Helium-hydride ion also gets a little bit of use as does helium hydride molecular ion. Helium-hydride-ion is used once. Helium hydride ion is in more than 100 papers and appears the most common after HeH+. My favourite, hydrogen helide is also a possible name, but also hardly used.

helium: helium hydride (only exists as an ion) According to the convention above, the following are "hydrogen compounds" and not "hydrides": [citation needed] oxygen: water ("oxidane" when substituted; synonym: hydrogen oxide), hydrogen peroxide; sulfur: hydrogen sulfide ("sulfane" when substituted) selenium: hydrogen selenide ("selane" when ...
The lightest heteronuclear ion is the helium hydride ion (HeH +). This is in contrast to a homonuclear ion , which contains all the same kind of atom, such as the dihydrogen cation , or atomic ions that only contain one atom such as the hydrogen anion (H − ).
