where are electrons located in a covalent bond?
between atoms
the idea of covalent bonding can be traced several years before 1919 to gilbert n. lewis, who in 1916 described the sharing of electron pairs between atoms. he introduced the "lewis notation" or "electron dot notation" or "lewis dot structure", in which valence electrons (those in the outer shell) are represented as dots around the atomic symbols. pairs of electrons located between atoms represent covalent bonds. multiple pairs represent multiple bonds, such as double bonds and triple bonds. an alternative form of representation, not shown here, has bond-forming electron pairs represented as solid lines.

coordinate covalent bond









































a coordinate covalent bond, also known as a dative bond or coordinate bond is a kind of 2-center, 2-electron covalent bond in which the two electrons derive from the same atom. the bonding of metal ions to ligands involves this kind of interaction. this type of interaction is central to lewis acid-base theory.

coordinate covalent bonding is pervasive. in all metal aquo-complexes [m(ho)], the bonding between water and the metal cation is described as a coordinate covalent bond. metal-ligand interactions in most organometallic compounds and most coordination compounds are described similarly.
