Single, double, and triple covalent bonds are represented by two, four, or six electrons in the overlapping region. The overlap between the two circles bear witness to the sharing of electrons between the two atoms. The more dots and crosses you see inside, … WebLewis Structure Examples. The Lewis electron dot structures of a few molecules are illustrated in this subsection. 1. Lewis Structure of CO2. The central atom of this molecule is carbon. Oxygen contains 6 valence electrons which form 2 lone pairs. Since it is bonded to only one carbon atom, it must form a double bond.
