Chemical Bonds PartI.Text-Translation: What hold matter together?In other words,why does glue stick, or what causes pieces of hard candy to stick together? Why is a diamond so hard; why is wax soft? 是什么维持物质在一起?换言之,为什么胶水能粘连?什么使硬糖块粘在一起?为什么钻石如此之硬,而...
Chemical bonding - Intermolecular, Forces, Attraction: Molecules cohere even though their ability to form chemical bonds has been satisfied. The evidence for the existence of these weak intermolecular forces is the fact that gases can be liquefied, that
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 theelementsin the...
A common theme uniting all of the models we have discussed is that bonding depends on the fall in potential energy that occurs when opposite charges are brought together. In the case of covalent bonds, the shared electron pair acts as a kind of “electron glue” between the joined nuclei....
You probably learned some time ago that chemical bonds are what hold atoms together to form the more complicated aggregates that we know as molecules and extended solids. Chemists talk about bonds all the time, and draw pictures of them as lines joining atom symbols. Teachers often identify the...
Re: Chemical bonds « Reply #1 on: November 16, 2018, 11:12:17 AM » Electrostatic interactions hold atoms together. We may think of this quasipermanent glue as bonds. Don't be worried about not have a clear understanding of what bonds are - chemists and physicists have been arguing...
However, in the latter case, multiorbital correlations were treated only in terms of two-orbital correlations, although the structure of multiorbital correlations is far richer; and, in the case of bonds established by more than two electrons, multiorbital correlations represent a more natural ...

It is the interaction between atoms and atomic bonding, to hold these atoms together and form different substances. According to their nature, the bonds can be categorized into two classes based on the bond energy. The primary bonds (>100 kJ/mol) are ionic, covalent, and metallic. The ...
