View the approximate locations of electrons in valence shells 1s through 4f.

An overview of chemical bonding and how valence electrons play a major role in these processes.

A summary of bonding terms and the importance of electrons in bonding.

This resource offers a brief description of the Octet rule, along with a quick practice, and answers to the exercise.

Students 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.

Find out how energy level models are represented on the Periodic Table of Elements.

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

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

This lesson will define the Octet Rule and how this effects an atom's stability. It is 4 of 5 in the series titled "Octet Rule."

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...

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.

A quiz on chemical bonding and valence electrons.

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

Slides 5 through 8 in this presentation from the McMaster University explain covalent bonding.

In this interactive activity from ChemThink, students will learn about covalent molecules and how the VSEPR theory predicts the shapes of covalently-bonded molecules.

This power point covers the molecular structure chapter from "An Introduction to Chemistry". It reviews the main ideas and shows many examples of covalent bonding from valence electrons. Also includes detailed steps to drawing lewis dot...

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...

Learn all about molecular structures in this easy-to-understand, audio book. See how valence electrons determine how atoms bond together, and look at the bonding inside some of the most common molecules around you.

A nice introduction to why carbon is the key to organic chemistry. Explains the role of valence electrons in the bonding of carbon and gives lots of "stick figures" models of simple hydrocarbons.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorail students will use the Periodic Table to identify and explain periodic trends, including atomic and ionic radii, electronegativity,...

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 lesson will define ionization energy. It is 1 of 3 in the series titled "Ionization Energy."

Students can use this chemistry tutorial to further their understanding of the families of elements on the Periodic Table of Elements.

This is a teacher's companion guide with lesson plans for the periodic table. It includes learning objectives, lecture notes, links to related sites, answers to frequently asked questions, and a glossary of related terms.
