Drawing Dot Structures and Lewis Diagrams
Completion requirements
Now that you understand the types of chemical bonds, we explore Lewis Dot Diagrams, a common way to draw covalently-bonded molecules. In Lewis dot diagrams, we use small dots to show the valence (outer shell) electrons of an atom. We can then combine the valence electrons of different atoms together to form covalent bonds, using a set of rules.
Watch the following videos in order. These four videos guide you through the steps for making Lewis dot diagrams for small molecules, and show worked examples.
