Herausgeber: Maksic, Zvonimir B. A chemical bond is an attractive force between atoms.
The localization of molecular orbitals is only a mathematical operation which does not involve any physic localization of the electrons.

J and K manage to compensate for the repulsion of the two protons until their separation is less than 100 pm (i.e the energy is negative up until this point), and a minimum in the energy is produced at 134 pm. *sofort verfügbar bei Bestellung eines Print-Titels, da es aufgrund der COVID-19-Situation zu Lieferverzögerungen kommen kann.

This minimum represents the formation of a chemical bond.
Many interpretations have been proposed.
, The Two-Electron Bond as a Molecular Building Block, Is hybridization just an artefact or does it reflect some physical reality?,
Nonpolar covalent bonds have a similar concept as polar covalent bonds; the atom with the higher electronegativity will draw away the electron from the weaker one. The loge theory is not more satisfying owing to the fact that loges with minimal fluctuation do not exist in all molecules. 7251, Luminy, F‐13288 Marseille, Cedex 9, France.Use the link below to share a full-text version of this article with your friends and colleagues.
Compounds that contain carbon (also called organic compounds) commonly exhibit this type of chemical bonding. The concept of a chemical bond is A) how two or more atoms are held together B) the sharing of nucleons C) how two or more electrons reside in an orbital D) how much energy it takes to remove an electron from a set of atoms E) none of the above .

It provides a concise introduction and critical evaluation of theoretical approaches in relation to experimental evidence. The pair of electrons which are shared by the two atoms now extend around the nuclei of atoms, leading to the creation of a molecule.

In spite of a current opinion, both models are not logically equivalent.
