An updated version of the Periodic Table has been released on 28 November 2016 which includes the recently added elements 113, 115, 117, and 118 and all standard and conventional atomic weights.
The standard atomic weights (abridged to five significant digits) and the conventional atomic weights are extracted from the most recent 2013 review published in PAC Vol. 88, No.3, pp. 265-291 (http://dx.doi.org/10.1515/pac-2015-0305). For ytterbium, the standard atomic weight is based on the 2015 review. An interval in square brackets provides the lower and upper bounds of the standard atomic weight for that element. For users needing an atomic-weight value for an unspecified sample without regard to the uncertainty, the conventional values are provided. No values are listed for elements which lack isotopes with a characteristic isotopic abundance in natural terrestrial samples. See PAC for more details or visit Commission II.1 at www.ciaaw.org. Visit www.isotopesmatter.com for an interactive version of the Periodic Table of the Elements and Isotopes.
A reprint of that table is included as this issue’s back cover tear-off page. To download the printable (PDF) version, see the following webpage:
