WebJan 1, 2024 · Elements are often categorized based on their general geochemical behaviors even though an element’s chemical behavior depends strongly on variables such as temperature, pressure, and chemical environment; the latter of which can dictate an element’s valence state and ability to form complexes. The Goldschmidt classification, developed by Victor Goldschmidt (1888–1947), is a geochemical classification which groups the chemical elements within the Earth according to their preferred host phases into lithophile (rock-loving), siderophile (iron-loving), chalcophile (sulfide ore-loving or chalcogen-loving), and atmophile (gas-loving) or volatile (the element, or a compound in which it occurs, is liquid or gaseous at ambient surface conditions).
