The Chemical Galaxy is a new periodic table designed by Philip Stewart in November 2004 based on the cyclical nature of characteristics of the chemical elements (which depend principally on the valence electrons). In 1951, Edgar Longman showed that arranging the elements in an ellipticalspiral helped reveal patterns in their properties. This gave the then-12-year-old Stewart the idea that it resembled a spiral galaxy. It is designed as an inspiring supplement to existing periodic tables.

Born Digital Ltd – The concept, the drawing of the spiral and the colour scheme were the work of P J Stewart. His design was illustrated and translated into digital form by Carl Wenczek of Born Digital Ltd.
The ChemicalGalaxy is a new periodic table designed by Philip Stewart in November2004 based on the cyclical nature of characteristics of the chemical elements (which depend principally on the valence electrons).
In 1951, Edgar Longman showed that arranging the elements in an ellipticalspiral helped reveal patterns in their properties.
This gave the then-12-year-old Stewart the idea that it resembled a spiralgalaxy.
This distinction is significant because hydrogen and helium (together with trace amounts of lithium) are the only elements that occur naturally without the nuclear fusion activity of stars.
Thus, the "metallicity" of a galaxy or other object is an indication of past stellar activity.
Abundance (atom fraction) of the chemical elements in Earth's upper continental crust as a function of atomic number.
