Hot atom chemistry
WebThe atom formed with an energy well in excess of the ambient thermal energy (not necessarily via a nuclear event), or highly charged is called a hot atom. Such atoms then dissipate most of their kinetic energy in the medium producing radiolytic changes in the surrounding system (those changes will be studied in radiation chemistry) and ...

H3+ is an electrically charged molecule, called an ion. It consists of three hydrogen atoms with only two, as opposed to a healthy three, electrons to share between them. Lacking a negatively charged electron, the molecule takes on a plus-one positive charge.
