The Elements According to Relative Abundance (A Periodic Chart by Prof. Wm. F. Sheehan, University of Santa Clara. CA 95053. Ref. Chemistry. Vol. 49.No.3. p. 17-18, 1976)
From the caption:
Roughly, the size of an element’s own niche is proportioned to its abundance on Earth’s surface, and in addition, certain chemical similarities.
Very nice.
A couple of suggestions for the graphically inclined:
- How does a proportionate periodic table of your state (in the United States, substitute other appropriate geographic subdivisions if outside the United States) compare to other states?
- Adjust your periodic table to show the known elements at important dates in history.
I first saw this in a tweet by Maxime Duprez.
