Chemistry Review
At this site by the Massachusetts Institute of Technology you can see a description of various types of chemical bonds, including covalent bonds, ionic bonds, and hydrogen bonds.

Periodic Table of the Elements
Go to this site by the Los Alamos National Laboratory to see an interactive periodic table. Click on any element in the table to learn more about that element.

Hydrogen Bonds
Visit this site to find out all about the hydrogen bonds that keep polar molecules together. Hydrogen bonds that form between water molecules account for some of the unique properties of water.

Chemistry Tutorial: The Chemistry of Water
At this site you can read about the polarity of water and the formation of hydrogen bonds. Scroll down to see an illustration of NaCl dissolved in water. NaCl in water breaks down into sodium (Na) and chlorine (Cl) ions.
