In chemistry, bond strength is the degree to which each atom joined to another in a chemical bond contributes to the valency of this other atom. Bond strength is intimately linked to bond order and 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 and hence stronger will be the bond. Overlap is necessary for the formation of molecular orbitals. This overlap can be calculated and is called the overlap integral.
Famous quotes containing the words bond and/or strength:
“Camillo. Prosperity’s the very bond of love,
Whose fresh complexion and whose heart together
Affliction alters.
Perdita. One of these is true:
I think affliction may subdue the cheek,
But not take in the mind.”
—William Shakespeare (1564–1616)
“Near this spot are deposited the remains of one who possessed Beauty without Vanity, Strength without Insolence, Courage without Ferocity, and all the Virtues of Man without his Vices. This praise, which would be unmeaning Flattery, if inscribed over human ashes, is but a just Tribute to the Memory of BOATSWAIN, a Dog.”
—John Cam Hobhouse (1786–1869)
