An Earth Scientist's Periodic Table of the Elements and Their Ions
The Earth Scientist's Periodic Table of the Elements and Their Ions is a periodic table designed to contextualize trends in geochemistry, mineralogy, aqueous chemistry, and other natural sciences. It is fundamentally different from the conventional periodic table in organizing entities by charge and consequently in showing many elements multiple times because of the multiple charges or valence states taken by those elements. These differences make this table much more effective in showing trends and patterns in geochemistry, mineralogy, aqueous chemistry, and other natural sciences.
