covalent bond
Covalent bonding as seen in a hydrogen chloride molecule. The hydrogen atom (H) shares an electron (yellow) with the chloride atom (Cl).

co·va·lent bond

(kō-vā′lənt)
A chemical bond formed when electrons are shared between two atoms. Usually each atom contributes one electron to form a pair of electrons that are shared by both atoms. See more at bond, coordinate bond, double bond, ionic bond.
