Isotopen en natuurlijke abundaties

Chemiepedia

Deze tabel noemt de massa en het percentage natuurlijk voorkomen van alle stabiele nucliden. Voor elementen zonder stabiel nuclide is de massa van het langlevende isotoop opgenomen. Nucliden die met een (*) zijn gemarkeerd komen niet vrij voor in de natuur of er kan geen zinvol natuurlijk voorkomen worden gegeven. De isotoopmassa’s zijn overgenomen van G. Audi, A.H. Warpstra Nucl. Phys A. 1993, 565, 1-65 en G. Audi, A.H. Warpstra Nucl. Phys A. 1995, 595, 409-480. De percentages natuurlijke abundanties zijn afkomstig van het 1997 rapport van de IUPAC Subcommittee for Isotopic Abundance Measurements door K.J.R. Rosman, P.D.P. Taylor Pure Appl. Chem. 1999, 71, 1593-1607
