WebBismuth carbonate (Bi 2 (CO 3) 3) is used to treat diarrhea and gastric ulcers. Once thought to be the heaviest stable isotope to exist in nature, experiments conducted in 2002 showed that bismuth-209 is unstable and decays into thallium-205 through alpha decay. Bismuth-209 has a half-life of roughly 19,000,000,000,000,000,000 years. WebAs shown in the figures, branching occurs in all four radioactive series, meaning the decay of a given species may occur in more than one way.
