*{{fnb|1}} The element does not have any stable nuclides, and a value in brackets, e.g. [209], indicates the mass number of the longest-lived isotope of the element. However, three elements, Thorium, Protactinium, and Uranium, have a characteristic terrestrial isotopic composition, and thus their atomic mass given.
*{{fnb|2}} The isotopic composition of this element varies in some geological specimens, and the variation may exceed the uncertainty stated in the table.
