Description: One of the jewels in the Chemical Education Digital Library is Periodic Table Live! (PTL). It is a periodic table accompanied by pictures, movies, atomic structures, and more information about the chemical elements. The site also includes tools for sorting and graphing its numerical data. Visitors can contribute information about their favorite elements by using the Periodic Table Wiki, which is listed under Collections on the main page of the ChemEd Collaborative wiki site. If you have special expertise about one or more of the elements, please share it at the Periodic Table Wiki. Even if you don't want to contribute, you can listen in as a community of chemists and educators get elemental.
