If a hydrogen atom loses its electron then it is then usually referred to as a protonproton, although it might be something else depending on the hydrogen isotope involved.
The following summarizes the recommended nomenclature, adapted from a webpage on the subject (see also the authorative references [2-3]):
General | $\ce{^1H}$ | $\ce{^2H}$ | $\ce{^3H}$ | |
---|---|---|---|---|
Atom (H) | hydrogen | protium | deuterium | tritium |
Cation (H+) | hydron | proton | deuteron | triton |
Anion (H-) | hydride | protide | deuteride | tritide |
Group (-H) | hydro | protio | deuterio | tritio |
Transfer of cation to substrate | hydronation | protonation | deuteronation | tritonation |
Replacement of hydrogen by a specific isotope | protiation | deuteriation (or deuteration) | tritiation |
