WebFeb 27, 2024 · Why does H2 exist? Hydrogen exists as a diatomic molecule, i.e.it can only exist by bonding to another hydrogen. You know that hydrogen has only one electron in its outermost and only shell. But in order to achieve a stable configuration, there must be two electrons in this shell. So two hydrogen atoms share their electrons through bonding.
