blending process that spreads double-bond character evenly over the atoms that participate in it. In ozone, for instance, each oxygen-oxygen bond is rendered equivalent by resonance, and each one has a mixture of single-bond and double-bond character (as indicated by its length and strength)....

A covalent bond may be single, double, or triple. A single bond (-) is when the atoms share two electrons. It is usually a sigma (σ) bond. For example, a water molecule has two hydrogen atoms and a central oxygen atom that are held together by two single covalent bonds. Each hydro...

2. Carbon monoxide (CO): Carbon monoxide features a triple bond between carbon and oxygen. Two of the three electron pairs in the triple bond are regular covalent bonds, while the remaining electron pair is a dative covalent bond, with carbon donating the electron pair to oxygen. 3. Sulfur...
There is a covalent bond between theoxygenand eachhydrogenin a watermolecule(H2O). Each of the covalent bonds containstwo electrons, one from a hydrogen atom and one from the oxygen atom. Both atoms share the electrons. A hydrogen molecule, H2, consists of two hydrogen atoms joined by a co...
This elongated bond has the interesting effect of suppressing the need for double bonds between oxygen and the central atom. The elongated bond concept is applied to about a hundred of molecules and ions and methodically compared to classical representations. It is shown that this new representation...
