Abstract

The geochemical table of the elements, with English, French, German, Spanish, and Russian key, contains the following data for each element: Geochemical character. Weight and structure —atomic number, atomic weight, weight of one atom, and electronic shell structure. Size and charge —atomic and ionic radii, atomic and ionic volumes, ionization potentials, electrostatic valances, co-ordinations, and radius ratios. Isotopic —naturally occurring isotopes with half lives and type of radiation decay. Thermodynamic —standard heat of formation (gas), standard free energy of formation (gas), logarithm of equilibrium constant (gas), and entropy at 25° C. (gas and solid). Mineralogic —common or geochemically significant minerals with per cent of element contained. Value —cost per unit weight or volume. Abundances in grams per metric ton —in sedimentary and igneous rocks; sea water (with transfer percentages); sulphide-, silicate-, and iron phase of meteorites; and the universe. Behavior during differentiation is shown in an idealized graph. Series —electromotive, electronegativity, ionic potential, Hofmeister, Fournet and Schutz, Schurmann, and pH series.
