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 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. Two p-orbitals forming a pi-bond.
