Legitimate Lands and Properties germanium disulfide lewis structure [27] Germanium is recovered as a by-product from sphalerite zinc ores where it is concentrated in amounts as great as 0.3%,[62] especially from low-temperature sediment-hosted, massive ZnPbCu(Ba) deposits and carbonate-hosted ZnPb deposits. In almost all cases, chemical bonds are formed by interactions of valence electrons in atoms. [10][17] With further material from 500kg of ore from the mines in Saxony, Winkler confirmed the chemical properties of the new element in 1887.
