Bismuth-209 ( Bi) is the isotope of bismuth with the longest known half-life of any radioisotope that undergoes α-decay (alpha decay). It has 83 protons and a magic number of 126 neutrons, and an atomic mass of 208.9803987 amu (atomic mass units). Primordial bismuth consists entirely of this isotope. See more Bismuth-209 was long thought to have the heaviest stable nucleus of any element, but in 2003, a research team at the Institut d’Astrophysique Spatiale in Orsay, France, discovered that Bi undergoes alpha decay with a half-life of … See more Because primordial bismuth is entirely bismuth-209, bismuth-209 is used for all of the normal applications attributed to bismuth, such as … See more • Isotopes of bismuth • Primordial radionuclide • List of elements by stability of isotopes See more Primordial In the red giant stars of the asymptotic giant branch, the s-process (slow process) is ongoing to produce … See more

WebScience Chemistry >Element 107, now named bohrium, was synthesized by German researchers by colliding bismuth-209 with chromium-54 to form a bohrium isotope and one neutron. Write the nuclear equation to represent this reaction. WebPolonium-210 is usually produced artificially in a nuclear reactor by bombarding bismuth-209 (a stable isotope) with neutrons. This forms radioactive bismuth-210, which has a … devoted otc catalog
