The Periodic Table site I like is www.webelements.com which has a link to their site targeted at students (www.webelements.com/webelements/scholar/). This shows them an entire periodic table. Clicking on each element brings up information about the element (number, weight, electron structure, etc) as well as real-world uses. There is also a downloadable program, although some of the more in-depth information still requires net access.
