Abstract

The Electrostatic-Covalent-Transfer, ECT, model provides a fit of bond energies for a large data base whose accuracy for the full data set exceeds that of any other reported approach. This result has important implications for teaching peridodic trends in ionic-covalent bonding and electronegativity in both general and inorganic chemistry. Several examples are discussed to illustrate the use of the parameters and tables of parameters are presented to encourage their application to new systems.
