Be sure to answer all parts. In 2006, an ex-KGB agent was murdered in London. Subsequent investigation showed that the cause of death was poisoning with the radioactive isotope 210Po, which was added to his drinks/food. (a) 210Po is prepared by bombarding 209Bi with neutrons. Write an equation for the reaction. Show the mass number and atomic number of all species. Tip: use the sup-subscript button to insert all symbols. (b) Who discovered the element polonium? Marie and Pierre Curie Enrico Fermi (c) The half-life of 210Po is 138 d. It decays with the emission of an αâparticle. Write an equation for the decay process. Show the mass number and atomic number of all species. Tip: use the sup-subscript button to insert all symbols. (d) Calculate the energy of an emitted αâparticle. Assume both the parent and daughter nuclei to have zero kinetic energy. The atomic masses are: 210Po (209.98285 amu), 206Pb (205.97444 amu), αâparticle (4.00150 amu). (Enter your answer in scientific notation). à 10 J (e) Ingestion of 1.0 mg of 210Po could prove fatal. What is the total energy released by this quantity of 210Po, assuming every atom decays? (Enter your answer in scientific notation). à 10 J
