A covalent bond is formed by two atoms sharing a pair of electrons. The atoms are held together because the electron pair is attracted by both of the nuclei.
In the formation of a simple covalent bond, each atom supplies one electron to the bond - but that doesn't have to be the case. A co-ordinate bond (also called a dative covalent bond) is a covalent bond (a shared pair of electrons) in which both electrons originate from the same atom.
Covalent bond
Hydrogen chloride has a covalent bond.
The bond between oxygen atoms is considered as covalent.
Covalent bond
A+ ionic bond
A covalent bond. nonmetal-nonmetal=covalent bond.
Covalent Bond occurs between two non metals.
A covalent bond is typical for compounds between nonmetals.
Covalent. There is no electronegativity difference between two atoms of the same element.
A double covalent bond and a coordinate covalent bond.
OCl2 is covalent compound and the bond between O and Cl is covalent
A polar covalent bond is a covalent bond between atoms in which the electrons are shared unequally.
