  1. ^ ا ب ج د ه و ز ح ط ي يا يب يج يد يه يو يز يح يط ك كا كب كج كد كه كو كز كح كط ل لا لب لج لد له لو لز لح لط The isotopic composition of this element varies in some geological specimens, and the variation may exceed the uncertainty stated in the table.
  2. ^ ا ب ج د ه و ز ح The isotopic composition of the element can vary in commercial materials, which can cause the atomic weight to deviate significantly from the given value.
  3. ^ ا ب ج د ه و ز ح ط ي يا يب يج يد يه The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given.
  4. ^ 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.
  5. ^ ا ب ج د ه و ز ح ط ي يا يب يج يد يه يو يز يح يط ك كا كب كج كد كه كو كز كح كط ل لا لب لج لد له لو 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.
  6. ^ This element has not been discovered/synthesized.
