Usage
Standard atomic weight, infobox element, isotopes of element.
Data source
- 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]
- Data templates:
- {{Infobox element/symbol-to-saw}} (parent template, no data)
|format=standard [default], abridged, formal-short-rounded
- {{Infobox element/symbol-to-saw/standard}}, Template:CIAAW2021
- {{Infobox element/symbol-to-saw/abridged}}
- {{Infobox element/symbol-to-saw/formal-short-rounded}}
Number formatting
- 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).
