WebJul 20, 2024 · As the atomic number increases, the zone of stability corresponds to a gradually increasing neutron/proton ratio. In the case of the heaviest stable isotope, Bi 83 209 for instance, the neutron/proton ratio is 1.518. If an unstable isotope lies to the left of the zone of stability in Figure 19.8. 1, it is neutron rich and decays by β emission. 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.
