 WebElements is website devoted to the periodic table.  It provides information about the physical properties, history, and reactivity of all of the elements.  In some cases, there are movies for downloading that show aspects of the reactivity of the element or one of its compounds.  The site also contains interesting chemistry trivia (e.g. the origin of the names of elements).  Finally, there are some excellent graphics for comparing the physical properties of all elements collectively.  You might find this site of value when studying Chapter 22.

A company called 3DChem.com has a website that shows the 3-dimensional structure of a large number of molecules that can be manipulated by you much including the VSEPR figures available in the table shown on this page.  The structures of the top 50 prescription medicines are available, as are 1600 structures of inorganic compounds (e.g. the structure of the gemstones Ruby and Garnet), and assorted other molecules (e.g. the molecules that give rise to the scents of garlic and cloves).
