i'm bored so ... what is the most common isotope of hydrogen? (i know the answers protium, I just want someone to talk to)

oh its easy, so basically there are three isotopes of hydrogen. and it is protium deutrium and tritium. actually in the unverse, protium slightly less than deutrium and deutrium is used to make heavy water which in itself sounds like an interesting name. and of course protium is the most special form of hydrogen as it is the only element without a neutron.
