웹2024년 12월 12일 · Uranium-235 undergoes fission, forming krypton-92, barium-141, and 3 neutrons. The mass of the uranium-235 is greater than the total mass of the products. … 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). haryana etenders.hry.nic.in
