Can H+ appear as stable gas or they react to form H2? Can H+ appear as stable gas or they react to form H2? Can H+ appear as stable gas or they react to form H2? Can H+ appear as stable gas or they react to form H2? thanks!

    $\begingroup$ There's a reason that the minimum character requirement is in place. It usually takes at least that much text to set up the background and explain what you have tried. $\endgroup$ – jonsca Aug 24 '16 at 1:29
  • $\begingroup$ @Mithoron it says 'Adding a bare proton to a molecule is a real event in the gas phase' so is it possible to produce a proton beam as we do easily with electron beams? even in vacuum, I don't care $\endgroup$ – ergon Aug 24 '16 at 12:32
  • $\begingroup$ Off course you can make proton beam, it's even used for therapy en.wikipedia.org/wiki/Proton_therapy but it's by no means a gas, not even plasma, but separated particles. In the future you need to word your questions properly and say exactly what you're asking. Also this is rather physics than chemistry. $\endgroup$ – Mithoron Aug 24 '16 at 13:15

A bare naked proton is one of the most reactive species known. Finding them in the gas phase is unlikely in terrestrial conditions. Additionally, there are some charge balance issues

However, hydrogen plasma is known to be abundant in the universe, forming the primary composition of most stars. This would be H+ ions swimming in a sea of electrons. It requires intense energy to keep this state, and without an input of heat the plasma will condense to hydrogen atoms, which will then form hydrogen gas.

  • $\begingroup$ though H+ are very common in liquids and cells, yet you say it's impossible to ionize H+ gas? $\endgroup$ – ergon Aug 24 '16 at 7:52
  • $\begingroup$ it's easy to produce a beam of electrons, isn't it that easy to produce a beam of protons? $\endgroup$ – ergon Aug 24 '16 at 12:29
  • $\begingroup$ Free H+ are not common. Electrostaticly interacting H+ (such as with a solvent) are very common. $\endgroup$ – Lighthart Aug 24 '16 at 17:30
