+
+# For several elements, the standard atomic weight A_r is given as an
+# atomic-weight interval with the symbol [a,b] to denote the set of
+# atomic-weight values in normal materials; thus, [a <= A_r(E) <= b].
+# The symbols a and b denote the lower and upper bounds of the
+# interval [a,b], respectively. The values in parentheses, following
+# the last significant digit to which they are attributed, are
+# uncertainties.
+#
+# Brackets [ ] enclosing a single value indicate the mass number of
+# the most stable isotope. For radioactive elements with atomic
+# numbers 95 or greater, the mass number of the most stable isotope is
+# not specified, as the list of studied isotopes is still
+# incomplete.
+
+# When composition mole fractions of isotopes are given, the atomic mass
+# of an element is given as the sum of the product(s) of mole
+# fraction(s) and the atomic masses of the relevant isotopes. When composition
+# mole fractions are not given, the atomic mass is given as
+#
+# * the mass of the most stable isotope, if available, or
+# * the standard atomic mass of the element, if available.
+#
+# If neither the most stable isotope nore a standard atomic mass is
+# available, no atomic mass for the element is given; the user must
+# select the isotope most suitable for their purposes.
+#
+# If the standard atomic mass is a range, the value given is the
+# midpoint of that range, which may differ from the value determined
+# from the sum of the products of composition mole fraction and isotope
+# atomic mass.
