Weight of a neutron?

  1. Apr 24, 2012 #1
    Hello all,
    Does anyone know the weight of a neutron? Or, better yet, does anyone know offhand the weight of hydrogen subscript 2 (hydrogen isotope with two neutrons)?
    Thanks!

    To clarify notation:

    H1 = ordinary hydrogen (no neutrons)
    H2 = deuterium (one neutron)
    H3 = tritium (two neutrons)

    Oh, oops! Looks like I had a discrepancy between the subscript and neutron number. I did mean tritium, but I'd be curious to know the weight of deuterium (the real H2) as well.

    those wikipedia articles have the answer

    Great. I'll take a look.

    Really, you should try to look this kind of information up yourself.
