Template:CIAAW2013/doc

{{CIAAW2013}} adds a full reference (<ref>...</ref>) for the standard atomic weight (A_{r, standard}) of chemical elements as defined by IUPAC (commission: CIAAW). The source is:

• Meija, Juris; et al. (2016). "Atomic weights of the elements 2013 (IUPAC Technical Report)". Pure and Applied Chemistry. 88 (3): 265–91. doi:10.1515/pac-2015-0305.

This template has options to use by refname, and as plain source (no <ref> tag). See #Options.

Notes

• This report was published in February 2016, while it documents the nominal 2013 CIAAW list publication.
• CIAAW publishes changes in the atomic weights biannually (nominally 2011, 2013, 2015, ...). See #CIAAW updated values.
• The {{Cite journal}} is filled here: {{CIAAW2013/cite journal}}.

CIAAW

Primarily, the atomic weights second here are defined by CIAAW [1]:

• "Standard Atomic Weights". Commission on Isotopic Abundances and Atomic Weights (CIAAW). 2015. Retrieved 2015-09-20. (68 elements)
• CIAAW also published additional lists in spreadsheet format (2013, no longer available). They had additional conventional values for trade usage, and some background information on the numbers and calculations. (12 elements: H, B, Br, C, Cl, Li, Mg, N, O, S, Si, Tl).

Coplen, Tyler B.; Brand, Willi A. (2013), Atomic weights of the elements 2013 (xls), CIAAW

• Some unstable elements can naturally occur, and so are listed (4 elements: Bi, Th, Pa, U)
• Additional values are those of the most stable isotopes, as given in List of chemical elements (34 elements). This source is not supported by the CIAAW publications.
• CIAAW site or table 1 in PAC, has footnotes g, m, r.

CIAAW updated values

  (This list: )

CIAAW may publish changes to atomic weights (including its precision and derived values). Since 1947, any update this is done in odd years nominally; the actual date of publication may be some time later.

* "2020" is an inconsistent year for change publcation: CIAAW maintains that only odd years, changes are publicised.
