Tin ( 50 Sn) is the element with the greatest number of stable isotopes (ten; three of them are potentially radioactive but have not been observed to decay). This is probably related to the fact that 50 is a "magic number" of protons. In addition, twenty-nine unstable tin isotopes are known, including tin-100 ( 100 Sn) (discovered in 1994) [4 ...

Iodine-124 is a proton-rich isotope of iodine with a half-life of 4.18 days. Its modes of decay are: 74.4% electron capture, 25.6% positron emission. 124 I decays to 124 Te. Iodine-124 can be made by numerous nuclear reactions via a cyclotron. The most common starting material used is 124 Te.
Isotopes of barium. Naturally occurring barium ( 56 Ba) is a mix of six stable isotopes and one very long-lived radioactive primordial isotope, barium-130, identified as being unstable by geochemical means (from analysis of the presence of its daughter xenon-130 in rocks) in 2001. [4] This nuclide decays by double electron capture (absorbing ...
There are 23 other unstable isotopes that have been characterized, the longest-lived being 79 Se with a half-life 327,000 years, 75 Se with a half-life of 120 days, and 72 Se with a half-life of 8.40 days. Of the other isotopes, 73 Se has the longest half-life, 7.15 hours; most others have half-lives not exceeding 38 seconds. List of isotopes
