In chemistry, chemical bond (CR:137) (LH:8) (TL:145) is an actuated attachment between two chemical species, e.g. atoms, ions, or molecules, resulting in the formation of a geometrical bound state or spatially stable configuration, mediated via chemical force mechanisms, e.g. Coulomb forces in ionic bonds or exchange forces in covalent bonds.

- “Although the chemical bond was first recognized and discussed at great length in classical terms, most physicists regarded the mature of the chemical bond as a profound mystery until Heitler and London qualitatively derived the exchange interaction [see: exchange force] and showed that this quantum mechanical behavior accounted for the observed properties of valency and stability. On the other hand, it is not uncommon to find molecular biologists using a classical description of DNA replication and coding to justify the statement that the living cells obey the laws of physics without ever once putting down a law of physics or showing quantitatively how these laws are obeyed by these processes.”
