Preferred Label : chemical bond;
IUPAC definition : When forces acting between two atoms or groups of atoms lead to the formation of a
stable independent molecular entity, a chemical bond is considered to exist between
these atoms or groups. The principal characteristic of a bond in a molecule is the
existence of a region between the nuclei of constant potential contours that allows
the potential energy to improve substantially by atomic contraction at the expense
of only a small increase in kinetic energy. Not only directed covalent bonds characteristic
of organic compounds, but also bonds such as those existing between sodium cations
and chloride anions in a crystal of sodium chloride or the bonds binding aluminium
to six molecules of water in its environment, and even weak bonds that link two molecules
of O sub 2 /sub into O sub 4 /sub , are to be attributed to chemical bonds.;
