WebThis forms bismuth-210 which has a half-life of 5 days. Bismuth-210 decays to polonium-210 through a beta decay. One of the most common places for polonium to concentrate in nature is in tobacco. As the radium in the soil decays, the electrically charged polonium ion adheres to dust WebThis radioactive isotope contains 92 protons and 235 neutrons. False. The balanced nuclear equation for the decay of radon-220 by α decay is 220/86 Rn = 216/84 Rn = 216/84 Po + 4/2 He. True. The sum of the mass numbers and the sum of the atomic numbers must be equal on both sides of a nuclear equation. True.
