pElement is an interactive reference tool on the periodic table. It features user selectable skins, 12 colored maps, find element tool, unit conversion tool, element index, and data index. The program contains extensive information on the elements including melting point, boiling point, density (solid, liquid and gas phases), year discovered, polarizability, oxidation states, X-ray energies, electron configuration, temperature coefficient of resistivity, crystal structures and lattice parameters of all stable phases at atmospheric pressure (190+ total phases), and half-lives and decay modes of 660+ radioactive isotopes. Extended features include a list of 23 fundamental constants, illustration of the activity series of metals, metric system prefixes, historical summary of superconducting materials and eNotes on chemistry fundamentals (2 modules). eNotes are colorfully illustrated electronic study guides which allow one to quickly review fundamental scientific concepts.
