Definition: A single bond is a chemical link between two atoms in which electrons are shared between them. Examples: There is a single bond between the oxygen and each hydrogen in a water molecule (H 2 O). Each of the covalent bonds contains two electrons-one from a hydrogen atom and one from the oxygen atom.
A less often mentioned type of bonding is metallic bonding. In this type of bonding, each atom in a metal donates one or more electrons to a sea of electrons that reside between many metal atoms. In this sea, each electron is free (by virtue of its wave nature) to be associated with great many atoms at once. single bond between two atoms corresponds to the sharing of one pair of electrons. The electron density of these two bonding electrons is concentrated in the region between the two atoms, which is the defining quality of a sigma bond.
