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