The General Chemistry Virtual Textbook, or Chem 1, is broken into several sections covering various aspects of topics related to chemistry. This section deals with hybrid orbitals and specifically the valence bond model.

An excellent tutorial that examines VSEPR and pairs of valence electrons. The valence shell electron pair repulsion concept is explored using animated models. Includes a VSEPR calculator. Use the toolbar on the left to navigate through...

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

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

This site from WebChem contains information on the subject of bonding with an emphasis on valence and core electrons.

Short slide show provides basic information about drawing Lewis dot structures for covalent compounds. Starts with anatomy of the atom, and then shows the relationship between atomic particles and the Periodic Table of Elements. Offers...

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.

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

Detailed explanation of Valence Shell Electron Pair Repulsion (VSEPR) Theory with examples and questions for the reader to check comprehension. Also includes step-by-step instructions for correctly building molecules using VSEPR Theory....

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

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.

Brief explanation from Frostburg State University of valence bond theory and an explanation of what chemical situation creates a valence bond between two atoms.

Presents examples of molecules that do not match the expected bond angles in the Valence-Shell Electron-Pair Repulsion Model. Requires Java.

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 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.

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

[Free Registration/Login may be required to access all resource tools.] The following online tutorial explains the basis of VSEPR theory. It helps students predict the shapes of molecules and polyatomic ions using VSEPR theory and it...

This site provides a detailed overview of atoms. Content explores an atom's structure, as well as what ions are, how atoms bond, what compounds are (including how to name compounds), and what isotopes are.

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...

A quiz on chemical bonding and valence electrons.

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

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