From Wikipedia, the free encyclopedia

The subtopic Isotopes/wikidata (2018) explores the option to use Wikidata containing isotopes information, and have enwiki infoboxes reading that data.

To consider, when going to centralise data: put all 120 Big Tables in one page (Wikipedia, working area). Make automatic processing possible (same setup & structure all). -DePiep (talk) 10:30, 21 December 2018 (UTC)[reply]

Notes

[edit]
  • Evaluated isotopic composition is for most but not all commercial samples.
  • The precision of the isotope abundances and atomic mass is limited through variations. The given ranges should be applicable to any normal terrestrial material.
  • Geologically exceptional samples are known in which the isotopic composition lies outside the reported range. The uncertainty in the atomic mass may exceed the stated value for such specimens.
  • Commercially available materials may have been subjected to an undisclosed or inadvertent isotopic fractionation. Substantial deviations from the given mass and composition can occur.
  • Values marked # are not purely derived from experimental data, but at least partly from systematic trends. Spins with weak assignment arguments are enclosed in parentheses.
  • Uncertainties are given in concise form in parentheses after the corresponding last digits. Uncertainty values denote one standard deviation, except isotopic composition and standard atomic mass from IUPAC, which use expanded uncertainties.
