#   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.
