A single bond is a type of chemical bond where two atoms share one pair of electrons. This bond is the simplest form of covalent bonding and is commonly found in many molecules, such as hydrogen gas (H₂) and water (H₂O). Single bonds allow atoms to achieve a more stable electron configuration, often resembling that of the nearest noble gas. In a single bond, the shared electrons are attracted to the nuclei of both atoms, creating a strong connection. The strength of a single bond can vary depending on the atoms involved, but it generally allows for rotation around the bond axis, giving the molecule flexibility in its shape.
