{{CIAAW2011}} adds a full reference (<ref>...</ref>) for the
standard atomic weight (Ar, standard) of chemical elements as defined by IUPAC commission
CIAAW (2011). The source is:
"Atomic weights of the elements 2011 (IUPAC Technical Report)". Pure Appl. Chem. 85 (5): 1047–1078. 29 April 2013.

This template has options to use by refname, and as plain source (no <ref> tag). See
#Options.
Notes
CIAAW publishes changes in the atomic weights biannually, nominally in uneven years.
