Question

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 α−particle. 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 α−particle. Assume both the parent and daughter nuclei to have zero kinetic energy. The atomic masses are: 210Po (209.98285 amu), 206Pb (205.97444 amu), α−particle (4.00150 amu). (Enter your answer in scientific notation). × 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). × 10 J
