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.
Up to three covalent bonds can form at one time in a molecule. In a single bond, one pair of electrons is shared between two atoms. A double bond shares two pairs of electrons; it is stronger than a single bond, but it also creates a less stable molecule because it is more reactive. The triple bond shares three pairs of electrons, making it the least stable covalent bond. Learn more about Atoms & Molecules
