top: covalent bonding in a water molecule center: metallic bonding in silver bottom: ionic bonding in sodium chloride chemical bond n. Any of several forces, especially the ionic bond, covalent bond, and metallic bond, by which atoms or ions are bound in a molecule or crystal. ...
Molecular orbital theory is introduced to explain magnetism, bond order, and hybridization, which will be important in later discussions of the chemistry of carbon. Intermolecular forces, including hydrogen bonding, are discussed with a special Case Study focusing on the special properties of water. ...
This siloxane polymer contains siloxane-reactive and cellulose-reactive groups which give it the potential of reaction with both the silicone water repellent film and the cotton surface. Its effect is apparent in the greater laundering durability of the properties imparted to the cotton by the ...
Chemical bonding, any of the interactions that account for the association of atoms into molecules, ions, crystals, and other species. When atoms approach one another, their electrons interact and tend to distribute themselves in space so that the total
Water, substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states. It is one of the most plentiful of compounds and has the important ability to dissolve many other substances, which was essential to
Chemical bonding peculiarities in the crystalline dihydrate of sodium iodide were examined by means of Bader's "Atoms in Molecule" theory and the energies of cation–anion, cation–water and anion–water contacts were estimated on the basis of the experimental data that were shown to provide insig...
Solid-state lanthanide (Ln) borides of the simple LnB6 composition not only exhibit exciting physical behavior, in particular magnetic properties, but their electronic structure and chemical bonding are particularly intriguing as well. To shed more light on the latter, we have performed quantum-chemi...
Water molecules tend to align themselves so that the negatively charged side of one molecule sits next to the positively charged end of an adjacent one. This creates a weak type of secondary bonding called hydrogen bonding. These bonds give water a crystal structure when it freezes, and this ...
