Brief rules for writing Lewis structures for simple compounds. Some examples are included.

This audio book, narrated by Mark Bishop, describes the formation of covalent bonds. Lewis dot structures help highlight the valence electrons used to determine which bonds form. Also find links to animations and tutorials about other...

This slide show explains the rules for writing Lewis structures and then demonstrates an example. It then provides a practice example for the student to try.

An extensive lesson from UCLA on drawing resonance structures. Includes several examples, and links to related topics. Practice problems are also provided.

Given descriptions, diagrams, scenarios, or chemical symbols, students will model covalent bonds using electron dot formula (Lewis structures).

Here is a Lewis dot structure diagram of acetic avid, as well as a few properties of this compound.

This PowerPoint presentation features 33 slides that explain chemical bonding and molecular shape.

A slideshow with several slides dedicated to electronegativity, the trend which is illustrated in the slide at this link. Others slides explain how the electronegativity can be used to determine bond character.

This page from the Department of Chemistry at Washington University provides attractive Lewis dot diagrams and three-dimensional models for many of the common polyatomic ions. The images will make your visit worthwhile.

A slide presentation with several slides dedicated to the topic of formal charges. Formal charges are explained, and examples are given. A practice example is provided.

[Free Registration/Login may be required to access all resource tools.] In this lesson, students learn ways to predict what type of ion a given element is likely to form.

Lists the exceptions to the octet rule and provides a discussion and diagrams explaining each one. Includes clear diagrams illustrating this concept.

This slide presentation contains a description of the octet rule, as well as many related topics.
