General | Latest Info

In almost all cases, chemical bonds are formed by interactions of valence electrons in atoms. To facilitate our understanding of how valence electrons interact, simple way of representing those valence electrons would be useful. The Lewis electron dot diagram is a representation of valence electrons of an atom that uses dots around the symbol of element. The number of dots equals the number of valence electrons in an atom. These dots are arranged to right and left and above and below the symbol, with no more than two dots on side. For example, Lewis electron dot diagram for calcium is simply figure 1 shows Lewis symbols for elements of the third period of the periodic table.

9.1 Lewis Electron Dot Diagrams

In almost all cases, chemical bonds are formed by interactions of valence electrons in atoms. To facilitate our understanding of how valence electrons interact, simple way of representing those valence electrons would be useful. The Lewis electron dot diagram is a representation of valence electrons of an atom that uses dots around the symbol of element. The number of dots equals the number of valence electrons in an atom. These dots are arranged to right and left and above and below the symbol, with no more than two dots on side. For example, Lewis electron dot diagram for hydrogen is simply {matheq}\mathbf{H}\mathbf{\cdot}{endmatheq} because side is not important,. Lewis electron dot diagram could also be drawn as follow: {matheq}\mathbf{\dot{H}}\; \; or\; \mathbf{\cdot}\mathbf{H}\; \; \; or\; \; \; \mathbf{\underset{.}H}{endmatheq} electron dot diagram for helium, with two valence electrons, is as follow: {matheq}\mathbf{He}\mathbf{:}{endmatheq} by putting two electrons together on same side, we emphasize the fact that these two electrons are both in 1 s subshell; this is common convention we will adopt, although there will be exceptions later. The next atom, lithium, has an electron configuration of 1 s 2 2 s 1, so it has only one electron in its valence shell. Its electron dot diagram resembles that of hydrogen, except the symbol for lithium is used. {matheq}\mathbf{Li}\mathbf{\cdot}{endmatheq} Beryllium has two valence electrons in its 2 s shell, so its electron dot diagram is like that of helium: {matheq}\mathbf{Be}\mathbf{:}{endmatheq} next atom is boron. Its valence electron shell is 2 s 2 2 p 1, so it has three valence electrons. The third electron will go on another side of the symbol: {matheq}\mathbf{\dot{Be}}\mathbf{:}{endmatheq} again, it does not matter on which side of the symbol electron dots are position. For carbon, there are four valence electrons, two in 2 s subshell and two in 2 p subshell. As usual, we will draw two dots together on one side, to represent 2 s electrons. However, conventionally, we draw dots for two p electrons on different sides. As such, electron dot diagram for carbon is as follow: {matheq}\mathbf{\cdot \dot{C}}\mathbf{:}{endmatheq} with N, which has three p electrons, We put single dot on each of three remaining sides: {matheq}\mathbf{\cdot}\mathbf{\dot{\underset{.}N}}\mathbf{:}{endmatheq} for oxygen, which has four p electrons, We now have to start doubling up on dots on one other side of symbol. When doubling up electrons, make sure that side has no more than two electrons. {matheq}\mathbf{\cdot}\mathbf{\ddot{\underset{.}O}}\mathbf{:}{endmatheq} {matheq}\mathbf{:}\mathbf{\ddot{\underset{.}F}}\mathbf{:}{endmatheq} with the next element, sodium, process starts over with a single electron because sodium has single electron in its highest - number shell, N = 3 shell. By going through the periodic table, we see that Lewis ' electron dot diagrams of atoms will never have more than eight dots around the atomic symbol. For atoms with partially filled d or F subshells, these electrons are typically omitted from Lewis electron dot diagrams.
