The elements according to relative abundance on Earth's surface

Periodic Table of Elements scaled to relative abundance.
Periodic Table of Elements scaled to relative abundance
Roughly, the size of an element's own niche is proportioned to its abundance on Earth's surface, and in addition, certain chemical similarities (e.g., Be and Al, or В and Si) are suggested by the positioning of neighbors. The chart emphasizes that in real life a chemist will probably meet O, Si, Al, . . . and that he better do something about it. Periodic tables based upon elemental abundance would, of course, vary from planet to planet. . . (Wm. F. Sheehan).
