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.o. A bond cannot be both covalent and ionic. A bond can be covalent, ionic or metallic. In covalent bonding electrons are shared, electrons are transferred in ionic bonding a â¦ nd electrons move about in a sea of electrons in metallic bonds.
