Description
The last hundred years chemists have come up with several effects to explain the chemical bonding. A list of the most common ones include hydridization, hypervalency, hyperconjugation, aromaticity, resonance, electronegativity, and different kinds of orbitals such as bonding, anti-bonding, non-bonding, HOMO, LUMO, SOMO, etc. Each of these theories is appropriately designed to describe a specific group of molecular systems, and may cause confusion or rise contradictions when applied to different systems. The ongoing discovery of "exotic" species urges an economic and clear theory which can explain the bonding in terms of the electrostatic forces and spin coupling. We presently show that the two principles "molecules are made of atoms" and "atoms bear excited electronic states" are sufficient to account for every chemical bond. Here we focus on the case of beryllium oxides, transition metal complexes such as Cr(CO)6 and Cr(N2)6, and "hypervalent" compounds.
