"WebElements is an award-winning online periodic table. There is a Scholar Edition for students as well as a Professional Edition. Researchers click on the symbol for any element on the periodic table displayed on the home page. Information given for each element includes the name of the element in several languages, essentials (name, symbol, atomic weight, etc.), description, and isolation. Sidebars provide well-known compounds that contain the element and more detailed information on the element's properties and history. The Scholar Edition provides more pictures demonstrating element structures and periodic properites.  Both versions are excellent teaching tools as well as helpful ready reference resources."--"Best Free Reference Web Sites 2001." RUSA Quarterly, Fall 2001; reviewed Apr. 4. 2001.
