IUPAC Standard Atomic Weights Revised (2005).

Atomic weights of elements with atomic numbers from 1-109 taken from this source.

Atomic Weights of the Elements 2001, Pure Appl.

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.

Note 4: The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given.

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 2: The isotopic composition of this element varies in some geological specimens, and the variation may exceed the uncertainty stated in the table.However, three elements, Thorium, Protactinium, and Uranium, have a characteristic terrestrial isotopic composition, and thus their atomic mass given. , indicates the mass number of the longest-lived isotope of the element. Note 1: The element does not have any stable nuclides, and a value in brackets, e.g.

For artificial elements the nucleon count of the most stable isotope is listed bracketsĬhemical series of the periodic table Alkali metals The number in parenthesis gives the uncertainty in the "concise notation" dis given in parenthesis next to the least significant digits to which it applies", e.g., 1.00794(7) stands for 1.00794 ± 0.00007. Each element's atomic number, name, element symbol, and group and period numbers on the periodic table are given. This is a list of chemical elements, sorted by atomic mass (or most stable isotope) and color coded according to type of element.
