Atomic Mac is a periodic table of the elements for the Mac. In addition to the usual information found in such programs, The Atomic Mac also contains a wealth of nuclear information on each isotope, including half life, decay mode, and daughter products. X-ray data (fluorescence and binding energies) is also available. A molecular weight calculator makes it easy to find the molecular weight of compounds. A shaded diagram showing the ranges of physical properties makes it easy to visualize relationships across the periodic table.
