e/Helium hydride ion

Information
has gloss	eng: The hydrohelium(1+) cation, HeH+, is a positively-charged ion formed by the reaction of a proton with a helium atom in the gas phase, first observed in 1925. It is the strongest known acid, with a proton affinity of 177.8 kJ/mol. This ion is also called helium-hydride molecular ion. It has been suggested that it should occur naturally in the interstellar medium. It is the simplest heteronuclear ion, and is comparable with the hydrogen molecular ion, H2+. Unlike H2+, however, it has a permanent dipole moment, which makes the spectroscopic characterization easier.
lexicalization	eng: helium hydride ion
instance of	(noun) any of various water-soluble compounds having a sour taste and capable of turning litmus red and reacting with a base to form a salt acid
