covalent bond
In a water molecule, each hydrogen atom (H) shares an electron (yellow) with the oxygen atom (O).

covalent bond

n.
A chemical bond formed by the sharing of one or more electrons, especially pairs of electrons, between atoms.

covalent bond

n
(Chemistry) a type of chemical bond involving the sharing of electrons between atoms in a molecule, esp the sharing of a pair of electrons by two adjacent atoms

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.
