    Neutron Weight
AI Thread Summary
The weight of a neutron is approximately 1.675 × 10^-27 kg. Tritium, the hydrogen isotope with two neutrons, has a weight of 3.0160492 u, where 1 u equals 1.660538921 × 10^-27 kg. The discussion also clarifies the notation for hydrogen isotopes: H1 is ordinary hydrogen, H2 is deuterium (one neutron), and H3 is tritium (two neutrons). Participants encourage checking reliable sources like Wikipedia for accurate information. Overall, the thread emphasizes the importance of self-research for scientific data.

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.
