Barium-138
Naturally occurring barium (56Ba) 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. This nuclide decays by double electron capture (absorbing two electrons and emitting two neutrinos), with a half-life of (0.5–2.7)×10 years (about 10 times the age of the universe). 웹2007년 12월 4일 · barium 138.9 lanthanum 178.5 hafnium 180.9 tantalum 183.9 tungsten 186.2 rhenium 190.2 osmium 192.2 iridium 195.1 platinum 197.0 gold 200.6 mercury 204.4 thallium 207.2 lead 209.0 bismuth (209) polonium (210) astatine (222) radon 87 88 Ra 89 Ac A: 고체원소 A: 기체원소 : 액체원소 : 합성원소 (223) francium 226.0 radium 227.0 ...
