Sodium Oxide having a chemical formula of Na2O, is a metal oxide. It is also known as an alkali metal oxide as it comprises two sodium and one Oxygen atoms. The compound is widely used in ceramics and glasses. Also, this molecule is different from the other organic molecules as it is made up of one Metal Sodium and one non-metal Oxygen. Such compounds are known as ionic compounds, as there are ionic bonds formed in such molecules.

In almost all cases, chemical bonds are formed by interactions of valence electrons in atoms. To facilitate our understanding of how valence electrons interact, a simple way of representing those valence electrons would be useful. A Lewis electron dot symbol or electron dot diagram or a Lewis diagram or a Lewis structure is a representation of the valence electrons of an atom that uses dots around the symbol of the element. The number of dots equals the number of valence electrons in the atom. These dots are arranged to the right and left and above and below the symbol, with no more than two dots on a side. It does not matter what order the positions are used. Figure 1.

Lewis used dots to represent the valence electrons in his teaching of chemical bonding. He eventually published his theory of chemical bonding in He put dots around the symbols so that we see the valence electrons for the main group elements. Formation of chemical bonds to complete the requirement of eight electrons for the atom becomes a natural tendency. Lewis dot symbols of the first two periods are given here to illustrate this point. In fact, the entire group column of elements have the same Lewis dot symbols, because they have the same number of valence electrons. Lewis dot structures are useful in explaining the chemical bonding in molecules or ions. When several dot structures are reasonable for a molecule or ion, they all contribute to the molecular or ionic structure making it more stable.

Now, remember that this is just a way to represent the arrangement of electrons for understanding the structure. The first two electrons in a valence shell are s electrons, which are paired. In the formation of sodium oxide two sodium atoms transfer their 2 outermost electrons to an oxygen atom. Check Your Learning What is the Lewis electron dot symbol for each element?
