Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.
A covalent bond is a bond between two nonmetals, where the electrons are essentially shared. For example water is H2O.Oxygen needs two more electrons to have a full valence (â¦ outer shell) and each hydrogen needs one electron, so they share electrons to form the stable compound water.An ionic bond is a bond between a metal and a nonmetal, where there is an exchange of electrons. covalent bond is a bond between two nonmetals, where the electrons are essentially shared. For example water is H2O.
