This page explains what electronegativity is, and how and why it varies around the Periodic Table. It looks at the way that electronegativity differences affect bond type and explains what is meant by polar bonds and polar molecules.

A good discussion of electronegativity and its effects on bond polarity and bond type.

Observe polarization of a molecule.

Good introduction and graphics make this a solid page for understanding the orbital role in bonding and molecular geometry. The author is a professor at Florida State University.

Florida State University provides a discussion of polarity of binary and polyatomic molecules, with tables and graphics.

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.

This general tutorial begins with an explanation of the polarity of the water molecule and the effects this polarity has on the properties of water. Goes on to introduce organic molecules and has a thourough tutorial on the third page.

This site is a personal site that gives "a simple view of covalent bonding" including explanations, diagrams, and examples.

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 module with animations, explanations, and questions about the importance of electrons in the structure of an atom. Understand the definition and locations of electrons in the atom. Explore the role of electrons in bonding, polarity,...

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

This activity helps students review basic covalent nomenclature.

Students develop their own water molecule model to help them understand the idea that water has a slight positive charge at one end of the molecule and a slight negative charge at the other.

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

The following module illustrates a method for determining if a molecule is polar or nonpolar.

Page uses movies and 3D images to explain how properties of water relate to polarity and hydrogen bonding.

Explore the change in potential energy when molecules are separated from each other or broken apart.

Ever wonder why solid ice floats in liquid water? In this video lecture you will explore the special properties of water. Learn "the science behind how hydrogen bonds keep the ice in your glass (and the polar ice caps) afloat". At the...
