Radon-222 is generated in the uranium series from the alpha decay of radium-226, which has a half-life of 1600 years. Radon-222 itself alpha decays to polonium-218 with a half-life of approximately 3.82 days, making it the most stable isotope of radon. Its final decay product is stable lead-206. In theory, Rn is capable of double beta decay to Ra, and depending on the ma… WebFor example, an atom of carbon (atomic number 6, so six protons) can have either 6 neutrons or 8 neutrons.
