San Le's Periodic Table
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
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
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
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).
