Template:Standard atomic weight of the elements/doc

From Wikipedia, the free encyclopedia

Usage

[edit]

Standard atomic weight, infobox element, isotopes of element.

Data source

[edit]
All values are as published by CIAAW.
The atomic weight (Ar) specifiers "standard atomic weight", "abridged atomic weight", "conventional atomic weight" are thus named and defined (numerical value as listed here) by IUPAC (CIAAW).[1][2]
|format=standard [default], abridged, formal-short-rounded
{{Infobox element/symbol-to-saw/standard}}, [3]
{{Infobox element/symbol-to-saw/abridged}}
{{Infobox element/symbol-to-saw/formal-short-rounded}}

Number formatting

[edit]
  • Per source, abridged numbers without stated uncertainty have uncertainty (1). So Ar, abridged(Be) = 9.0122, reads 9.0122(1).
  • All numbers are formatted through {{val}}. This introduces the small space as 1000-grouping (per MOS:DIGITS).

CIAAW value updates

[edit]
  (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.
