8. A computer method for exhibiting the properties and structure of matter on a visual display unit using a data entry device connected to a data processing system having an atomic structure program means for constructing mathematical atomic models, and a text/graphic interactive user interface for permitting a user to interact with and perform operations on said atomic structure program means via said data entry device and said visual display unit, said method comprising the steps of: storing an atomic data base containing atomic information for use by said atomic structure program means for constructing said mathematical atomic models; displaying on said visual display unit atomic select buttons and said atomic information in response to selections made by said user via said atomic select buttons and said data entry device; displaying a plurality of element select buttons labeled with said atomic information to form a periodic table of chemical elements on said visual display unit; selecting one of said element select buttons via said data entry device and said visual display unit; displaying on said visual display unit, in response to said selecting of one of said element select buttons, a plurality of isotope select buttons labeled with isotope information from said atomic information, said isotope information corresponding to the isotopes of said one of said chemical elements; selecting one of said isotope select buttons via said data entry device and said visual display unit; displaying on said visual display unit, in response to said selecting of one of said isotope select buttons, the values of selected physical properties for the isotope corresponding to said isotope select button; and activating said atomic structure program means to construct said mathematical atomic models corresponding to said isotope select button.
