Chapter 19, Problem 19.103(choose chapter or problem)
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. (b) Who discovered the element polonium? (Hint: See Appendix 1.) (c) The halflife of 210Po is 138 d. It decays with the emission of an particle. Write an equation for the decay process. (d) Calculate the energy of an emitted 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), 4 2 (4.00150 amu). (e) Ingestion of 1 g of 210Po could prove fatal. What is the total energy released by this quantity of 210Po?
