[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will describe the structure and polarity of a water molecule. They will also describe the hydrogen bonding that occurs in...

A learning module giving the definition of a covalent bond, the compounds and elements they make up and why they form. Module includes reading and review questions.

Each amino acid has at least one amine and one acid functional group as the name implies. The different properties result from variations in the structures of different R groups. The R group is often referred to as the amino acid side...

Frostburg State University provides a brief explanation to the question of why small hydrogen molecules, such as OH, NH, and FH, are very polar.

This section in the online textbook describes how to tell if a molecule is polar or non polar. Detailed steps and examples are good references. Also find links to presentations and chapter maps for other chemistry topics.

Explore the water molecule, and understand how it is a polar molecule.

Created to teach students of the 21st century, SOPHIA is bringing electronegativity straight to your fingertips. Become the commander of your own learning experiences as you take part in this interactive lesson and help make learning...

A model that explores why electrons are so important in chemistry. Investigate electron clouds, what happens when two atoms come together, and chemical polarity.

In this online biology textbook, learn about atoms and molecules as they relate to life. Find out about topics such as electrons and energy, chemical bonding, and chemical reactions.

This is a Java tutorial showing the simple voltaic (or galvanic) electrical cell, which is the most basic type of "wet" cell and demonstrates the fundamental chemistry behind batteries.

Problem sets, tutorials, and activities related to biochemistry.

[Free Registration/Login may be required to access all resource tools.] Covers structure of water molecule, hydrogen bonding on water, polarity of water molecule, and bond angles of water molecule.

Some molecules can be either left- or right-"handed." The left- and right-handed molecules have the same number and type of atoms, and their chemical structures look identical, but they are actually mirror images of each other. Many...

This site is provided for by the McMaster University. Slides 34-36 in this presentation define electronegativity and relate it to bond polarity.

[Free Registration/Login may be required to access all resource tools.] Explains hydrogen bonds including why they form and changes of state.

This slide show on atomic bonds contains several slides on electron affinity. Other topics include covalent, Sigma and Pi bonds, and atomic bonding in solids.

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