包层模- IUPAC 2005 standard atomic weights (mean relative atomic masses) are listed with uncertainties in the last figure in parentheses [M. E. Wieser, Pure Appl. Chem.78, 2051 (2006)].
These values correspond to current best knowledge of the elements in natural terrestrial sources. For elements that have no stable or long-lived nuclides, the mass number of the nuclide with the longest confirmed
half-life is listed between square brackets.
- Elements with atomic numbers 112 and above have been reported but not fully authenticated.
