Relative atomic mass is shown with five
significant figures. For elements have no stable
nuclides, the value enclosed in brackets
indicates the mass number of the longest-lived
isotope of the element.
However three such elements (Th, Pa, and U)
do have a characteristic terrestrial isotopic
composition, and for these an atomic weight is
tabulated.
