Discussion Overview

The discussion revolves around the weights of neutrons and hydrogen isotopes, specifically deuterium (H2) and tritium (H3). Participants seek clarification on the weights of these isotopes and the neutron itself, exploring both theoretical and practical aspects of atomic mass.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant asks for the weight of a neutron and the weight of hydrogen subscript 2, indicating a need for clarity on isotopes.
  • Another participant provides the weight of tritium as 3.0160492 u and references the unified atomic mass unit.
  • Links to Wikipedia articles on neutrons and deuterium are shared, suggesting these sources contain relevant information.
  • A participant clarifies the notation for hydrogen isotopes, defining H1 as ordinary hydrogen, H2 as deuterium, and H3 as tritium.
  • There is a correction regarding the initial confusion between the subscript and neutron number, with a participant expressing curiosity about the weight of deuterium as well.
  • One participant encourages others to look up the information themselves, implying a preference for self-research over direct answers.

Areas of Agreement / Disagreement

The discussion does not reach a consensus on the weights of the isotopes, and multiple viewpoints regarding the need for clarification and self-research are present.

Contextual Notes

Participants reference external sources for atomic weights, indicating potential limitations in the discussion regarding the accuracy and completeness of the information provided.

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!

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.
