"Elements" is a software package that provides data and properties for the elements on the periodic table. This information has been derived from the "CRC Handbook of Chemistry and Physics, 72nd Edition". The program uses the organizing power of the periodic tables to access fundamental characteristics of each element. "Elements" provides a brief description for each element, which can be displayed by selecting the element from the periodic table that appears on the program's main screen. One element can be selected at a time, or a number of elements can be selected simultaneously in order to compare data. The calculation program also enables one to determine molecular weights of compounds. The book also provides data for each of these fields: atomic number, atomic weight, atomic radius, density, melting point, boiling point, critical temperature, resensitivity, thermal conductivity, specific heat, heat of fusion, thermal expansion coefficient, crust fraction, ocean fraction, reduction thermal expansion, ionization potential, electron configuration, oxidation state. "Elements" provides an on-screen definition. To use "Elements", an IBM or IBM-compatible computer, DOS 2.0 or higher, and at least 256MB of internal memory (RAM) is needed.
