However, three elements, thorium, protactinium, and uranium, have a characteristic terrestrial isotopic composition, and thus their atomic mass given.
- 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 The isotopic composition of this element varies in some geological specimens, and the variation may exceed the uncertainty stated in the table.
- 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given.
- 1 2 3 4 5 6 7 8 The isotopic composition of the element can vary in commercial materials, which can cause the atomic weight to deviate significantly from the given value.
- ↑ 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.
