The Atomic Mac is the award winning periodic table of the elements for the Macintosh. 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. No other periodic table of the elements has more data than The Atomic Mac! X-ray data (fluorescence and binding energies) is also available, as well as electron shell information and alpha particle energies. In addition you can view the visible spectra, and get a table of wavelengths and relative amplitudes. 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. Data is displayed for the following physical properties: Density Heat of Vaporization Heat of Fusion Specific Heat Thermal Conductivity Linear Expansion Coefficient Melting Point Boiling Point Atomic Radius Covalent Radius Magnetic Susceptability Electrical Resistivity Electron Affinity Electric Dipole Polarizability State (gas, liquid, solid) Photoelectric Work Function Electronegativity Crystal Structure Abundance in Earth's Crust Abundance in Earth's Sea Abundance in Earth's Atmosphere Abundance in Solar System Number of Isotopes Number of Naturally Occuring Isotopes Number of Stable Isotopes Photon Interactions Visible Light Spectra Magnetic Dipole Moment Electric Quadrupole Moment Nuclear Spin ©2002 Black Cat Systems.
