BondingMain article: Chemical bond
Atoms sticking together in molecules or crystals are said to be bonded with one another. A chemical bond may be visualized as the multipole balance between the positive charges in the nuclei and the negative charges oscillating about them. More than simple attraction and repulsion, the energies and distributions characterize the availability of an electron to bond to another atom.
A chemical bond can be a covalent bond, an ionic bond, a hydrogen bond or just because of Van der Waals force. Each of these kinds of bonds is ascribed to some potential. These potentials create the interactions which hold atoms together in molecules or crystals. In many simple compounds, Valence Bond Theory, the Valence Shell Electron Pair Repulsion model (VSEPR), and the concept of oxidation number can be used to explain molecular structure and composition.
Similarly, theories from classical physics can be used to predict many ionic structures. With more complicated compounds, such as metal complexes, valence bond theory is less applicable and alternative approaches, such as the molecular orbital theory, are generally used. See diagram on electronic orbitals.

Famous quotes containing the word bonding:
“At the heart of male bonding is this experience of boys in early puberty: they know they must break free from their mothers and the civilized world of women, but they are not ready yet for the world of men, so they are only at home with other boys, equally outcast, equally frightened, and equally involved in posturing what they believe to be manhood.”
—Frank Pittman (20th century)
“Attachment to a baby is a long-term process, not a single, magical moment. The opportunity for bonding at birth may be compared to falling in lovestaying in love takes longer and demands more work.”
—T. Berry Brazelton (20th century)
“The bottom line on bonding with multiples seems to be that if you see bonding as a static eventa moment in time at which you must have eye contact and skin contact simultaneously with two or more infantsyou may indeed be in trouble.”
—Pamela Patrick Novotny (20th century)
