Notes

  • Note 1: 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 or characteristic isotopic composition.
  • Note 2: The isotopic composition of this element varies in some geological specimens, and the variation may exceed the uncertainty stated in the table.
  • Note 3: The isotopic composition of the element can vary in commercial materials, which can cause the atomic weight to deviate significantly from the given value.
  • Note 4: The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given.
  • Note 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.
