Abstract

Stability constants of metal complexes of edta with main group and transition metals are correlated with properties of the elements and cations (ion charge, atomic and ionic radii, ionization energies and electronegativities) and interpreted with an ionic bonding model including a covalent contribution. Enthalpy and entropy contributions are discussed. It is shown how chemists recognize patterns in data with the help of a general theory and so develop a model.
