There are 39 known isotopes and 17 nuclear isomers of tellurium (52 Te), with atomic masses that range from 104 to 142. These are listed in the table below. Naturally-occurring tellurium on Earth consists of eight isotopes. Two of these have been found to be radioactive: 128 Te and 130 Te undergo double beta decay with half-lives of, respectively, 2.2×10 24 (2.2 septillion) years (the longest ...
