Hydrogenium (ab verbis Graecis antiquis ὕδωρ: "aqua", et γεννάω: "facere") est elementum chemicum primum systematis periodici. Numerus est protonum unus.

Sunt isotopia tria:

- Hydrogenium (Protium) 11H sine neutronibus in nucleo
- Deuterium 12H unum neutron in nucleo habens
- Tritium 13H duo neutrona in nucleo habens

Tritium non est stabile, sed radios emittit.

Hydrogenium in statu normali (298 K) aeriformis est. Status aggregationis liquidus sub 15.45 K est, solidus sub temperatura 14.05 K.
