History of the recommended atomic-weight values*
TABLE 1. Compilation and retrospective evaluation of
the IUPAC-recommended (standard) atomic-weight Ar(E)
values from 1882 to 1997
[Z
is the atomic number. E is the symbol of the chemical element. Ar(E)
is the recommended atomic-weight value adjusted, where appropriate,
to the 12C = 12 scale. U[Ar(E)]
is that year's estimated uncertainty in the standard atomic-weight value.
D[Ar(E)] is our estimate of the error in the
standard atomic-weight value and is the difference of that year's Ar(E)
from the latest standard Ar(E) value. D/U is
the ratio D[Ar(E)] / U[Ar(E)]
