In chemistry, bond strength is measured between two atoms joined in a chemical bond. 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 bond order Chemistry (in Greek: χημεία) is the science of matter and its interactions with energy and itself (see physics, biology). ... Properties For alternative meanings see atom (disambiguation). ... A chemical bond is the phenomenon of atoms being held together in molecules or crystals. ... In chemistry, valency is the power of an atom of an element to combine with other atoms measured by the number of electrons which an atom will give, take, or share to form a chemical bond. ... Bond order is the number of bonds between a pair of atoms. ...

Bond strength can be quantified by:

• bond energy: requires lengthy calculations, even for the simplest bonds.
• bond dissociation energy

Another criterion of bond strength is the qualitative relation between bond energies and the overlap of atomic orbitals of the bonds (Pauling and Mulliken). The more these overlap, the more the bonding electrons are to be found between the nuclei. This overlap can be calculated and is called the overlap integral. In chemistry, bond energy (E) is a measure of bond strength in a chemical bond. ... In chemistry, bond dissociation is a process in which a specific bond is cleaved to give two new species. ... The term orbital has several meanings: in physics and chemistry it is used to describe an atomic electron configuration, see also molecular orbital and atomic orbital. ... Linus Carl Pauling (February 28, 1901 – August 19, 1994) was an American physical chemist, widely regarded as the premier chemist of the twentieth century. ... Robert Sanderson Mulliken (June 7, 1896-October 31, 1986) was an American physicist and chemist, primarily responsible for the elaboration of the molecular orbital method of computing the structure of molecules. ... Properties The electron is a subatomic particle. ... Plural: nuclei In chemistry and physics, the nucleus (atomic nucleus) is the collection of protons and neutrons in the center of an atom that carries the bulk of the atoms mass and positive charge. ... In calculus, the integral of a function is a generalization of area, mass, volume, sum, and total. ...
