standard atomic weight
(
A
r, standard
) of chemical elements as defined by IUPAC (commission:
CIAAW
). The source is:

- Notes
- This report was published in February 2016, while it documents the
2013
CIAAW list publication.
- As CIAAW publishes the atomic weights biannually, in 2015 the website published a new list of standard atomic weights.
[2]
It appears that in 2015, only the formal standard atomic weight of
ytterbium
(
70
Yb) was changed wrt the "2013" publication.
[3]
In 2017, no changes were published at all.

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). It has 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, T. B.; Brand, W. A. (2013).
"Atomic weights of the elements 2013 (xls)"
. CIAAW
. Retrieved
2015-05-26
.
- 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.
