Template:Standard atomic weight of the elements/ciaaw-list-of-updates

{{align|right|{{nowrap|1= {{mono|1=(This list: {{view||edit|template=Standard atomic weight of the elements/ciaaw-list-of-updates}}}})}}}} 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.

2009 {{main other||{{tlx|CIAAW2009}}}} (introducing interval notation; Ge):

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

2021 {{main other||{{tlx|CIAAW2021}}}} (all elements listed); (4 values changed; introduced new symbol; merge "conventional" into "abridged" columns; change uncertainty notation (use "±")
