Description: Presents an experiment in which the masses of a helium atom and a polonium atom are determined. Shows how alpha particles are collected from decaying polonium to provide a sample of helium., Shows in detail the indirect methods used to determine the mass of a polonium atom. Emphasizes laboratory techniques in general and illustrates the special precautions necessary when handling radioactive materials. Explains the mathematical calculations applied to mass, volume, and density relationships to determine the mass of a atom.
