Abstract

AbstractThe hypertorus electron model is applied to the chemical bond. As a consequence, the bond topology can be determined. A linear correlation is found between the normalized bond area and the bond energy. The normalization number is a whole number. This number is interpreted as the Lewis's electron pair. A new electron distribution in the molecule follows. This discovery prompts to review the chemical bond, as it is understood in chemistry and physics.

Highlights

The topological analysis of the electron density has provided useful information about the bonding in a molecule
Not much progress has been made to reveal the fundamental features of chemical bonding postulated by Lewis, i.e. the electron pair
According to Lewis structures there are bonding electron pairs in the valence shell of an atom in a molecule, and there are nonbonding pairs or lone pairs in the valence shell of many of the atoms in a molecule. It has not been seen any evidence of electron pairing in the topological analysis of the electron density

Summary

Introduction

The topological analysis of the electron density has provided useful information about the bonding in a molecule. According to Lewis structures there are bonding electron pairs in the valence shell of an atom in a molecule, and there are nonbonding pairs or lone pairs in the valence shell of many of the atoms in a molecule It has not been seen any evidence of electron pairing in the topological analysis of the electron density. The deuteron presents three different shapes: a torus, an sphere inside another sphere and two separated spheres [3] These are the three possible intersections between a three dimensional space, that cut a hypertorus in half [4, 5, 6]. When the bond area is divided by a whole number, a linear correlation between the bond area and the bond energy occurs This whole number is interpreted as the electron pair. First time evidences of the Lewis electron’s pair are found
