## Notes

[edit | edit source]

1. ↑ 1.00 1.01 1.02 1.03 1.04 1.05 1.06 1.07 1.08 1.09 1.10 1.11 1.12 1.13 1.14 1.15 1.16 1.17 1.18 1.19 1.20 1.21 1.22 1.23 1.24 1.25 1.26 1.27 1.28 1.29 1.30 1.31 1.32 1.33 1.34 1.35 The element does not have any stable nuclides, and a value in brackets, e.g. [209], indicates the mass number of the longest-lived isotope of the element. However, three elements, Thorium, Protactinium, and Uranium, have a characteristic terrestrial isotopic composition, and thus their atomic mass given.
2. ↑ 2.00 2.01 2.02 2.03 2.04 2.05 2.06 2.07 2.08 2.09 2.10 2.11 2.12 2.13 2.14 2.15 2.16 2.17 2.18 2.19 2.20 2.21 2.22 2.23 2.24 2.25 2.26 2.27 2.28 2.29 2.30 2.31 2.32 2.33 2.34 2.35 2.36 2.37 2.38 The isotopic composition of this element varies in some geological specimens, and the variation may exceed the uncertainty stated in the table.
3. ↑ 3.00 3.01 3.02 3.03 3.04 3.05 3.06 3.07 3.08 3.09 3.10 3.11 3.12 3.13 3.14 The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given.
4. ↑ 4.0 4.1 4.2 4.3 4.4 4.5 4.6 4.7 The isotopic composition of the element can vary in commercial materials, which can cause the atomic weight to deviate significantly from the given value.
5. ↑ The atomic weight of commercial Lithium can vary between 6.939 and 6.996--analysis of the specific material is necessary to find a more accurate value.
