Goldschmidt periodic table classification. Modern periodic table showing 118 elements from hydrogen to oganesson, colour-coded according to how they are found in nature. This classification is named after the Swiss-Norwegian geochemist Victor Goldschmidt (1888-1947). The types are: siderophile (dark purple), chalcophile (lighter purple), lithophile (blue), atmophile (turquoise), very rare or synthetic (light blue). Atmophiles are associated with the atmosphere; lithophiles react with oxygen and form light minerals; siderophiles form heavier minerals; chalcophiles react with sulphur and are between lithophiles and siderophiles in density within the Earth.
