The following sites may prove useful for mastering the chapter on Chemical Bonding. In order to access the site, click on its title.
- Molecular and Ionic Compounds
This site distinguishes molecular from ionic compounds. How do you tell one from another?
- Electronegativity
This site is a brief introduction to the concept of electronegativity and how it influences bonding.
- Writing Lewis Structures
This site is a step-by-step tutorial for writing electron dot structures. It also has practice problems.
- Valence Shell Electron Pair Repulsion (VSEPR)
This is well written site describing how to determine the shapes of molecules. Some good animation is included.
- Molecular Geometries
This is a 56-page PowerPoint show covering the common topics found in a discussion of molecular geometry. It takes a minute to load, but after that all the screens advance very rapidly. You need to have PowerPoint 2000 installed on your computer. If you don't, download the PP reader for free from the Microsoft site on the Internet.
- Chemical Bonding
This is a 73-page PowerPoint show covering the topics of ionic and covalent bonding, Lewis dot structures, polarity, dipole attractions, hydrogen bonding, and oxidation numbers. It takes a minute to load, but after that all the screens advance very rapidly. You need to have PowerPoint 2000 installed on your computer. If you don't, download the PP reader for free from the Microsoft site on the Internet.
