The Periodic Table has too much information for the three of us to memorize. This great amount of information led us to use a few reference materials. It's only fair we give the makers of these materials some credit, so here we go.

WINTPE- A very easy-to-use version of the Periodic Table for Windows or Windows 95 machines.

BK PERIODIC LIBRARY- is an interactive periodic table made for the Microsoft Windows environment. But it is more than simply another computerized version of the standard periodic table. This one takes full advantage of your computer's capabilities to give you an in-depth look at the elements.
