Learners draw and interpret Lewis dot diagrams for individual atoms and both covalent and ionic compounds.

This lesson will demonstrate how to draw a Lewis Dot diagram for elements. It is 4 of 4 in the series titled "Lewis Dot Diagrams of Elements."

This lesson will demonstrate how to draw a Lewis dot diagram for a molecule that has single bonds. It is 2 of 2 in the series titled "Lewis Dot Diagrams of Molecules - single bonds."

Find out how molecular bonding is represented by Lewis dot diagrams.

Learners will use colored fruit loops to organize valence electrons to develop and master the basics of Lewis Dot diagrams. They will develop processing and critical thinking skills and also master a model of bonding.

This lesson will demonstrate how to draw a Lewis dot diagram for a molecule which has a double bond. It is 2 of 2 in the series titled "Lewis Dot Diagrams of Molecules: Double Bonds."

This lesson will demonstrate how to draw a Lewis dot diagram for a molecule which has a triple bond. It is 2 of 2 in the series titled "Lewis Dot Diagrams of Molecules: Triple Bonds."

An excellent lesson on writing Lewis structures. Examples shown include ammonium ion, carbon dioxide and the carbonate ion.

This lesson include biographical information, but it focuses on the concepts behind the "dot diagrams" that Lewis introduced.

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

This slide presentation contains a few slides that will be useful for students learning to write Lewis structures. A discussion of multiple bonds is included, and clear examples are shown.

This colorful page goes over the proper techniques for writing Lewis structures for elements. This is a great place to begin learning how to write Lewis structures. When you are ready for a more advanced lesson, follow the link to learn...

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

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.

Given descriptions, diagrams, scenarios, or chemical symbols, students will model ionic bonds using electron dot formulas.

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

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.

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.

This site talks about ionic, polar covalent, and non-polar covalent bonding.

Six middle school chemistry lessons about the periodic table and bonding complete with handouts and animations.

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.
