The arrangement of the elements in this chart is from Helen Pawlowski's model of the atom and her Circular Periodic Table, as described in her book The Visualization of the Atom (Riverton, UT: Pawlowski Family Trust, 1990). That book is reviewed in these pages. The icons are those created for my periodic table.
