This Web site from the American Chemical Society features an interactive Periodic Table with the use of Shockwave. The information presented is divided into three sections. In the first, Periodic Table, students will find attributes such as melting point and molar heat capacity for the elements. The second part illustrates the electron configurations of each of the elements, helping students to better understand the concept. The last section allows users to plot data based on the elements' attributes including atomic radius and electro negativity. Working with this site, high school and college students are able to improve their chemical knowledge.
