Be sure to answer all parts. Radon (Rn) is the heaviest and the only radioactive member of Group 8A(18), the noble gases. It is a product of the disintegration of heavier radioactive nuclei found in minute concentrations in many common rocks used for building and construction. In recent years, health concerns about the cancers caused from inhaled residential radon have grown. If 1.00 x 1015 atoms of radium (Ra) produce an average of 1.373 x 104 atoms of Rn per...
