pElement is an advanced interactive reference tool on the periodic table. It contains over 65 information items on each element, user selectable skins, 12 colored maps, find element tool, unit conversion tool and more! Examples of information provided in the program include melting point, boiling point, density, year discovered, oxidation states, electronegativity, electron configuration, 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. Academic site licenses are available.
