The bond valence model is an evolution of Pauling's electrostatic valence principle first enunciated in 1929. Recent improvements in crystal structure determination have allowed the model to become more quantitative. Unlike other models of inorganic chemical bonding, the bond valence model is simple, ...

The app is based on the chemical bonding, molecular structure, bonding chemistry, formation of chemical bond, bonding in chemistry. Students can explore and practice the interactive activities and view the 3D simulations and videos for better understanding. The colorful 3D simulations, videos and ...
chemical bond is the key to understanding all chemistry, be it inorganic, physical, organic or biochemistry. In the form of a question and answer tutorial the fundamental concepts of chemical bonding are explored. These range from the nature of the chemical bond, via the regular hexagonal ...

The bond energy of ionic bonds is larger, so the melting point of ionic compounds is higher. However, when the ionic bonds are broken, the anion and anion will be formed, that is, in an aqueous solution or in a molten state. So the easy way to tell if it's an ionic compound is ...

1.3.1 HYDROGEN BONDING A hydrogen bond is a bond between a functional group A-H and an atom or group of atoms B in the same or a different molecule. With exceptions to be noted later, hydrogen bonds are assumed to form only when A is oxygen, nitrogen, or fluorine and when B is ...

So although the "chemical bond" (as a physical object) may be no more than a convenient fiction,chemical bonding, which leads to the near-infinity of substances (31 million in mid-2007), lies at the very core of chemistry. The forces that hold bonded atoms together are basically just the...
