Question:
(a) 210Po is prepared by bombarding 209Bi with neutrons. Write an equation for the reaction.
(b) Who discovered the element polonium?
(c) The half-life of 210Po is 138 d. It decays with the emission of an a particle. Write an equation for the decay process.
(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), 42α (4.00150 amu).
(e) Ingestion of 1 mg of 210Po could prove fatal. What is the total energy released by this quantity of 210Po?
