Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond. Mar 31, 2013 A Sure-Fire Way to Draw Lewis Structures! Lewis structures are a way to write chemical compounds where all the atoms and electrons are shown. Demos Lewis Dot Structures This demo will convert a skeletal figure, provided by a drawing in the HTML5 SketcherCanvas component on the left, into a Lewis Dot Structure in the Canvas on the right. When you are finished drawing your 2D structure, click on the Get Lewis Dot Structure button to see the result. A step-by-step explanation of how to draw the Li2S Lewis Dot Structure.For Li2S we have an ionic compound and we need to take that into account when we draw. These theories, which include Lewis structures, VSEPR, and hybridization, are simple models that help predict chemical properties. However, Lewis dot structures and hybridization are approximations that may or may not match reality. We should verify the usefulness of our simple predictions with molecular orbital theory. If the theoretical calculations are done carefully, we can learn a lot about chemical structure by comparing our Lewis structures. Every chemistry student has to learn how to draw Lewis Dot Structures. The key is to understand the steps and practice. Lewis Structures are important to learn because they help us predict: the shape of a molecule. How the molecule might react with other molecules. The physical properties of the molecule (like boiling point, surface tension, etc.).

Please draw a structure with the integrated molecule editor (JSME) on the left-hand side. The 3D structure will automatically be calculated by CORINA Classic and displayed on the right-hand side in the Jmol app. Below the JSmol/Jmol visualization app window, two links are provided to download the structure as PDB or Molfile.
The functionality of this online service is also described in a short user guide saved as slide show or PDF file.

Remarks: In case of a slow internet connection you can disable the interactivity by unchecking the checkbox 'Interactive'. Update the 3D model manually by clicking on the 'Update' button. The structure editor will also read MOL files using the PASTE command (Ctrl+V) or context menu (right mouse-click). Finally, some HTML 5 compatible browsers support the drag and drop functionality of Molfiles.

Note: This online service requires that JavaScript is enabled in your internet browser. If the visualization window on the right-hand side is not successfully loaded, click on the 'Java' button to start the Java based display of the 3D structure. In this case the Java plug-in (version 1.4 or higher) should be installed and enabled in your browser. The previous non-interactive version of the CORINA Classic online service is also still available.
