Gn Lewis uses dots to represent the valence of electrons in his teaching of chemical bonding. He eventually published his theory of chemical bonding in 1916. He put dots around symbols so that we see valence electrons for main group elements. Formation of chemical bonds to complete the requirement of eight electrons for atom become natural tendency. Lewis Dot symbols of the first two periods are given here to illustrate this point. In fact, entire group of elements have the same Lewis Dot symbols, because they have the same number of valence electrons. Lewis Dot Structures are useful in explaining chemical bonding in molecules or ions. When several Dot structures are reasonable for molecule or ion, they all contribute to molecular or ionic structure, making it more stable. Representation of molecular or ionic structure by several structures is called resonance. The more stable the Dot structure is, more it contributes to the electronic structure of molecule or ion. You need to know what Dot Structure represent, how to draw them, and what formal charges for atoms in structure are. When several Dot structures are possible, consider resonance structures to interpret real structure. Apply some simple rules to explain which resonance structures are major contributors to electronic structure. Formal charge on any atom in the Lewis Structure is the number assigned to it according to the number of valence electrons of atom and number of electrons around it. The formal charge of an atom is equal to the number of valence electrons, N ve minus number of unshared electrons, N us. E and half of bonding electrons, N be some practice of assigning formal charge is necessary before you master this technique. Some examples of drawing Lewis Structure and assigning formal charge are given below. Formal charge is a hypothetical charge from Dot Structure. Formal charges in structure tell us the quality of the Dot structure. When several structures with different electron distributions among bonds are possible, all structures contribute to the electronic structure of the molecule. These structures are called resonance structures. The combination of all these resonance structures represents real or observed structure. Lewis structures of some molecules do not agree with observed structures. For such a molecule, several Dot Structures may be draw. All Dot Structures contribute to real structure. More stable structures contribute more than less stable ones. For resonance structures, skeleton of molecule stays in the same relative position, and only distributions of electrons in resonance structures are different. Let us return to {matheq}{SO2}{endmatheq} molecule. The molecule has a bent structure due to lone pair of electrons on {matheq}{S}{endmatheq} in last structure that has formal charge, there is single {matheq}{S-O}{endmatheq} Bond and double {matheq}{S=O}{endmatheq} Bond. These two bonds can switch over, giving two resonance structures as shown below.
