Is a proton a hydrogen cation and vice versa?

  1. Aug 26, 2012 #1

    I was wondering if it could be said that any proton can be identified as a hydrogen cation, and any hydrogen cation as a proton.

    Any free proton is a hydrogen cation.
    There are hydrogen isotopes with neutrons (deuterium and tritium) - therefore, hydrogen cations can be a single proton or (proton+neutron) or (proton+2 neutrons).
    Actually there are more hydrogen isotopes, but they are so short-living that it is pointless to talk about electrons and chemistry.
