When I was a softmore in high school in 1988, I did a redesign of the Periodic Table of Elements for a chemistry class assignment. I think what I came up with is interesting so I thought I would share it with everyone. Recently, I looked on the Internet for other alternate Periodic Tables, and haven't seen any like mine so I am hoping I created it first. If you have seen this arrangement before, please email me about it and where you saw it. I also have forgotten most of the chemistry I learned, so I may have made some mistakes in describing the table below.

My intention with this arrangement was to illustrate the way electrons would fill up the shells of a particular atom. This is a very natural way to arrange the elements, and some of the tables developed by others are variations of this, such as the The Filling Periodic Table and Albert Tarantola's Table.

The advantages of my table are the following:

It illustrates how the shells are filling up.
I build from the center line alternating back and fourth between elements to further the concept of shells filling up. This means that elements at the top of a column only lack one electron for the completion of that shell while those at the bottom have completely filled shells.
Elements that were previously vertically aligned are now horizontally aligned.
You can expand the size of the table indefinitely.

On November 12th, 2007, I found this incredibly extensive collection of periodic tables at the Chemogenesis Webook which is a site dedicated to telling "the story of chemical structure & reactivity emerging from the periodic table of the elements and bifurcating into the rich, complex and extraordinary science that we know and experience". This site is a fantastic resource for those interested in understanding chemistry. I submitted my table to the site which kindly included it among the others there.

Here are two images of the table you can look at. The first is of printable size (600 x 528) if you print in landscape mode. The second is a larger image(1800 x 1584).
