A hydrogen bond is a weak force of attraction that exists between two atoms or ions with opposite charges. For example, the hydrogen-oxygen bonds in water are polar bonds. The hydrogen end of these bonds are slightly positive, and the oxygen ends are slightly negative. Two molecules of ...
bond formation, much of theirpragmaticunderstanding of bonds is expressed in simple intuitive models. These models treat bonds as primarily of two kinds—namely,ionicandcovalent. The type of bond that is most likely to occur between two atoms can be predicted on the basis of the location of ...
II. CHEMICAL BONDING The electronic structure of atoms determines the type of bond between the atoms concerned. As we said earlier, chemical bonds may be classified as primary or secondary depending on the extent of electron involvement. Valence electrons are involved in the formation of primary...

the oxygen atom on anadjacentwater molecule. The structure of liquid water is believed to consist ofaggregatesof water molecules that form and re-form continually. This short-range order, as it is called, accounts for other unusual properties of water, such as its highviscosityandsurface ...
The Nature of the Chemical Bond and the Structure of Molecules and Crystals An Introduction to Modern Structural Chemistry. By Prof. Linus Pauling. (The George Fisher Baker Non-resident Lectureship in Chemistry at Cornell University.) Pp. xiv + 429. (Ithaca, N.Y.: Cornell University Press; ...
The book begins with an overview of structural information on surface adsorbates and discusses the structure of a number of important chemisorption systems. Chapter 2 describes in detail the chemical bond between atoms or molecules and a metal surface in the observed surface structures. A detailed de...
Well-defined conjugates between two amine-containing molecules are more reliably prepared by thiolating one or more amines on one of the biomolecules and converting one or more amines on the second biomolecule to a thiol-reactive functional group such as ...
This chapter discusses the basic building blocks of materials: atoms and molecules. It describes the atom at an elementary level, origin of the interatomic forces responsible for bond formation, the three principal strong bonds, and the secondary bonds. The chapter also defines the molecule and ...
intermolecular potential energyFigure 16: An intermolecular potential energy curve. The graph shows how the potential energy of two molecules varies with their separation. The energy minimum is shallower than for the formation of a chemical bond between two atoms, as depicted in Figure 10 and indica...
