Bond energy — In chemistry, bond energy ( E ) is a measure of bond strength in a chemical bond. For example the carbon hydrogen bond energy in methane E (C–H) is the enthalpy change involved with breaking up one molecule of methane into a carbon atom and 4… … Wikipedia
Bond strength — In chemistry, bond strength is measured between two atoms joined in a chemical bond [JerryMarch] . It is the degree to which each atom linked to a central atom contributes to the valency of this central atom. Bond strength is intimately linked to … Wikipedia
Bond-dissociation energy — In chemistry, bond dissociation energy (BDE) or D0, is one measure of the bond strength in a chemical bond. It is defined as the standard enthalpy change when a bond is cleaved by homolysis,[1] with reactants and products of the homolysis… … Wikipedia
Bond dissociation energy — In chemistry, bond dissociation energy, D0 or BDE, is one measure of the bond strength in a chemical bond. It is defined as the standard enthalpy change when a bond is cleaved by homolysis, [GoldBookRef |title=Bond dissociation energy… … Wikipedia
bond energy — noun a) The sum of the bond dissociation energies of all the bonds in a molecule b) The average or typical bond dissociation energy of a particular type of bond … Wiktionary
Chemical bond — A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electromagnetic force attraction between opposite charges, either between electrons and… … Wikipedia
Reactive empirical bond order — The reactive empirical bond order (REBO) model is a widely used function for calculating the potential energy of covalent bonds and the interatomic force. In this model, the total potential energy of system is a sum of nearest neighbour pair… … Wikipedia
Carbon-oxygen bond — A carbon oxygen bond is a covalent bond between carbon and oxygen and one of the most abundant in organic chemistry and biochemistry. [ Organic Chemistry John McMurry 2nd Ed.] Oxygen has 6 valence electrons and prefers to share two electrons in… … Wikipedia
Valence bond theory — In chemistry, valence bond theory explains the nature of a chemical bond in a molecule in terms of atomic valencies. [Murrel, JN, Kettle, SF Tedder, JM The Chemical Bond , John Wiley Sons (1985) ISBN 0 471 90759 6] Valence bond theory summarizes… … Wikipedia
Modern valence bond theory — is the term used to describe applications of valence bond theory with computer programs that are competitive in accuracy and economy with programs for the Hartree Fock method and other molecular orbital based methods. The latter methods dominated … Wikipedia
Sigma bond — In chemistry, sigma bonds (σ bonds) are the strongest type of covalent chemical bond. Sigma bonding is most clearly defined for diatomic molecules using the language and tools of symmetry groups. In this formal approach, a σ bond is symmetrical… … Wikipedia
