Standard Model Instability

It seems that in the standard model, the deuteron is not completely stable, but rather very long lived. t'Hooft writes at the bottom of page 3 "Thus, because of the Cabibbo rotation, a proton and a neutron (two baryons equal six quarks) may annihilate to form two antileptons, one of electron and one of muon type. The factors exp(- 16pi /g^2) = exp(- 4pi * 137 * sin theta_W)" This calculation is elaborated here: https://physics.stackexchange.com/a/288913/10991 to conclude a lifetime of 10^180 seconds.

Should Deuterium glow tube be used for lede image?

Would it make more sense for File:Deuterium discharage tube.jpg to be used as the lead image instead, or maybe along with, the isotope highlighted on the table of nuclides? After all, we don't just put images of elements highlighted on the periodic table for their lede sections. ✨ΩmegaMantis✨^blather 18:30, 14 December 2023 (UTC)

Template:Tl does not seem to prescribe any standard for the image. Might be useful to ask Wikipedia:WikiProject Elements to coordinate this across the many such articles. DMacks (talk) 19:35, 14 December 2023 (UTC)

Added the gas discharge tube photo for now, since the project seems to favor actual photos of elements, and someone else has already suggested it. Mrfoogles (talk) 17:47, 30 June 2024 (UTC)

If there's any opposition this can go on the WikiProject talk page Mrfoogles (talk) 17:49, 30 June 2024 (UTC)

Symbol

IUPAC recommends that the chemical symbol for deuterium should be ²H, rather than D. I strongly agree with that recommendation, for multiple reasons. This article should follow IUPAC's recommendation; for instance, writing ²H₂O rather than D₂O (see "Heavy water"). Solomonfromfinland (talk) 22:02, 12 March 2024 (UTC)

Section "Data for molecular deuterium"

That section contains also data concerning atomic deuterium, and deuterium combined with other elements, such as HDO . This seems to contradict the heading of the section. Ekisbares (talk) 08:59, 17 July 2024 (UTC)

Sources

See the article, "Isotopes of hydrogen". In it, the section, "Hydrogen-2 (deuterium)", doesn't cite any sources. Please add some sources there. Solomonfromfinland (talk) 16:30, 13 November 2024 (UTC)
