Lewis Diagrams

Learn more on how to use and make a Lewis diagram using these printable diagrams! Lewis structures are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. Lewis structures show each atom and its position in the structure of the molecule using its chemical symbol. Lines are drawn between atoms that are bonded to one another (pairs of dots can be used instead of lines). Take a look at the following CH3 Lewis structure below.

The Lewis diagram above is the CH3 Lewis structure. The CH3 Lewis structure has a total of 8 valence electrons. This includes the electron represented by the negative charge in CH3. In Lewis structures, the elemental properties and reactions are determined only by electrons in the outer energy levels. Electrons in completely filled energy levels are ignored when considering properties. Simplified Bohr diagrams which only consider electrons in outer energy levels are called Lewis Symbols. More examples of the Lewis structures can be seen in the following diagrams.

Lewis Symbol consists of the element symbol surrounded by “dots” to represent the number of electrons in the outer energy level as represented by a Bohr Diagram. The number of electrons in the outer energy level is correlated by simply reading the Group number.  A Lewis diagram depicts a molecule using an element symbol to represent the nucleus and core electrons of each atom. Valence electrons are represented by lines for electron pair bonds and dots for un-bonded electrons. See the diagrams below.
