Helium hydride ion

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 the first compound formed in the Universe after the Big Bang. The ion was first produced in a laboratory in 1925. It is stable in isolation, but extremely reactive, and cannot be prepared in bulk, because it would react with any other molecule with which it came into contact. Noted as the strongest known acid—stronger than even fluoroantimonic acid—its occurrence in the interstellar medium had been conjectured since the 1970s, and it was finally detected in April 2019 using the airborne SOFIA telescope. (Wikipedia).

Properties of Hydrogen | Environmental Chemistry | Chemistry | FuseSchool

Hydrogen is a gas at room temperature, and is the first element in the periodic table. It has the chemical symbol H, but is usually found as a diatomic molecule of H2. It reacts with oxygen to form water. Hydrogen is a colourless, odourless gas that burns and can form an explosive mixt

How Scientists Found the First Type of Molecule in the Universe | SciShow News

Around a quarter of a million years after the Big Bang, the very first molecule, helium hydride was formed. Now scientists have confirmed that molecule is still being made, and they found it with some help from a high flying airplane. Host: Caitlin Hofmeister SciShow has a spinoff podca
