Understanding the energy it takes to build or break chemical bonds is essential for scientists and engineers in a wide range of innovative fields, including catalysis, nanomaterials, bioengineering, environmental chemistry, and space science. Reflecting the frequent additions and updates of bond dissociati...
The Oxygen is two electrons short of a full outer shell. The Hydrogen atoms need to gain an extra electron to complete their outer shell which can hold two electrons. Transferring electrons would require too much energy in this case. What happens is that the electrons areshared. The Oxygen s...

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...

The precise definition of bonding energy is described in another lesson and is not important here. For the moment you only need to know that in any stable structure, the potential energy of its atoms is lower than that of the individual isolated atoms. Thus the formation of methane from its...

but this did not work. She then tried drinking a mix of the energy drink Cobra and Coke for two weeks, which she stopped because she suffered from stomach aches, nausea, and dizziness. Feeling that they were too young to have a family on their own, she and her boyfriend decided to con...
energy relationships are surveyed for various bond types. The ionic model is applied to the crystal lattice energy calculations, introducing Madelung's constants. Electronic properties of solids, particularly band gaps, are related to the type of the chemical bonding. The concept of electronegativity ...
