atomic weight is given as a single value with an uncertainty that includes both measurement uncertainty and uncertainty due to isotopic abundance variations. Element has only one isotope that is used to determine its standard atomic weight.... Weights on the Periodic Table are given as standard atomic weight, which is the average mass of a given element in mass units. One mass unit is equal to 1/12 the mass of a single carbon-12 atom.

With the benefit of hindsight, we know that Mendeleev's periodic table was underpinned by false reasoning. Mendeleev believed, incorrectly, that chemical properties were determined by atomic weight. Of course, this was perfectly reasonable when we consider scientific knowledge in 1869.
- atomic weight is given as a single value with an uncertainty that includes both measurement uncertainty and uncertainty due to isotopic abundance variations. Element has only one isotope that is used to determine its standard atomic weight.
- * Standard atomic weight The formal standard atomic weight may look like 4.002602(2) for helium , and [1.0078, 1.0082] for hydrogen. The "( n )" is the uncertainty.
