List of isotopes by symbol
This article is licensed under the GNU Free Documentation License. It uses material from the Wikipedia article "List_of_isotopes_by_symbol".

A table of chemical elements ordered by atomic number and color coded according to type of element. Given is each element's name, element symbol, atomic mass (or most stable isotope), and in some cases a list of isotopes with their own article.

The name of the element links to an article about isotopes of that element, and the symbol links to the main article about the element.

Notes

  1. ^ a b c d e f g h i j k l m n o p q r s t u v w x y z aa ab ac ad ae af ag ah ai aj ak al am The isotopic composition of this element varies in some geological specimens, and the variation may exceed the uncertainty stated in the table.
  2. ^ a b c d e f g h 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. ^ a b c d e f g h i j k l m n o 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. ^ a b c d e f g h i j k l m n o p q r s t u v w x y z aa ab ac ad ae af ag ah ai aj 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.
