H+3 yakatanga kuwanikwa naJ. J. Thomson muna 1911. Paakanga achidzidza nezvemhando dzemhando dzemagetsi eplasma, akawana chimwe chinhu chinoshamisa. Achishandisa nzira yekutanga ye mass spectrometry, akawana huwandu hwakawanda hwemamolecular ion ine mass-to-charge ratio ye3. Akataura kuti mikana miviri chete yaive C4+ kana H+3. Sezvo C4+ yaizove isingaite uye chiratidzo chakakura zvakanyanya mugasi rehydrogen yakachena, akapa mhando yacho nenzira kwayo seH+3. Mubvunzo: Ndiani akawana mamorekuru ion anonzi H+3 muna 1911?
