The helium hydride ion or 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. It can also be viewed as protonated helium. It is the lightest heteronuclear ion, and is believed to be … Visa mer The helium hydrogen ion is isoelectronic with molecular hydrogen (H 2). Unlike the dihydrogen ion H 2, the helium hydride ion has a permanent dipole moment, which makes its spectroscopic characterization … Visa mer Discovery in ionization experiments Hydridohelium(1+), specifically [ He H] , was first detected indirectly in 1925 by T. R. Hogness and E. G. Lunn. They were injecting protons of known energy into a rarefied mixture of hydrogen and helium, in order to study the … Visa mer • Dihydrogen cation • Trihydrogen cation Visa mer Preparation Since HeH cannot be stored in any usable form, its chemistry must be studied by forming it in situ. Reactions with organic substances, for example, can be studied by creating a tritium derivative … Visa mer From decay of tritium The helium hydride ion is formed during the decay of tritium in the molecule HT or tritium molecule T2.
