| According to J.N. Spencer (JCE No. 3 p.182 1991) base of quantum-chemical interpretations are ‘unteachable'. We have developed an approach that helps explaining major chemical phenomena (covalent bonding, chemical kinetics and catalysis) without introducing quantum chemical entities. Our approach and a General Chemistry text book synopsis utilizing it are presented at www.ITChem.com. Based on that approach we have developed a theory of metallic bonding and explained the differences between bonds in metals and non-metallic compounds. While atoms of non-metals are connected via static two-electron covalent bonds, atoms in solid metals are linked by dynamic one-electron bonds. We have built quantitative models that explain how that bonding difference determines dissimilarity between properties (primarily thermo and electrical conductivity) of metals and non-metals. |
