WebStandard atomic weight of tantalum was last revised in 2005 to Ar (Ta) = 180.947 88 (2) and its isotopic composition was further revised in 2024 with no effect to the standard atomic weight. The minor isotope, 180 Ta, is radioactive with a very long half-life of more than 10 13 a. It is the last quasi-stable isotope to be discovered. Tantalum is estimated to make up about 1 ppm or 2 ppm of the Earth's crust by weight.
