How did Nicolas-Louis Vauquelin discovered chromium?
Nicolas-Louis Vauquelin discovered chromium by boiling crocoite (lead Chromate) with potassium carbonate. Reduction of the yellow salt with carbon produced a metal that he named “chromium” because of its color.
What did Louis Nicolas Vauquelin do?
Nicolas-Louis Vauquelin, (born May 16, 1763, Saint-André-d’Hébertot, France—died Nov. 14, 1829, Saint-André-d’Hébertot), French chemist who discovered the elements chromium (1797) and beryllium (1798).

Where did vauquelin discover Beryllium?
In 1798, he discovered beryllium in beryl and isolated chromium in lead ore obtained from Siberia. Vauquelin also discovered quinic acid, asparagines, camphoric acid, and several other organic substances.
Where can chromium be found?
chromite
Chromium is found mainly in chromite. This ore is found in many places including South Africa, India, Kazakhstan and Turkey. Chromium metal is usually produced by reducing chromite with carbon in an electric-arc furnace, or reducing chromium(III) oxide with aluminium or silicon.
Where can beryllium be found?
Beryllium is most often found in the minerals beryl and bertrandite. It is found in the Earth’s crust and mostly in igneous (volcanic) rocks. Most of the world’s beryllium is mined and extracted in the United States and Russia with the state of Utah supplying nearly two-thirds of the world’s beryllium production.
What country discovered beryllium?
Elemental (metallic) beryllium was isolated in 1828 by two chemists, working independently: Antoine Bussy (France) and Friedrich Wöhler (Germany).
Does chromium have an odor?
No taste or odor is associated with chromium compounds. The metal chromium, which is the chromium(0) form, is used for making steel. Chromium(VI) and chromium(III) are used for chrome plating, dyes and pigments, leather tanning, and wood preserving. What happens to chromium when it enters the environment?
What is a symbol of copper?
Cu
Copper/Symbol
copper (Cu), chemical element, a reddish, extremely ductile metal of Group 11 (Ib) of the periodic table that is an unusually good conductor of electricity and heat. Copper is found in the free metallic state in nature.
Where was Nicolas Louis Vauquelin born and raised?
French chemist, was born at Saint-André-d’Hébertot in Normandy on the 16th of May 1763. His first acquaintance with chemistry was gained as laboratory boy to an apothecary in Rouen (1777-79), and after various vicissitudes he obtained an introduction to Antoine François Fourcroy, in whose laboratory he was an assistant from 1783-91.
When did Louis Louis Vauquelin discover red lead?
…discovered by the French chemist Louis-Nicolas Vauquelin in 1797; the following year he isolated the metal by the carbon reduction of crocoite, or red lead, a chromate mineral whose brilliant hue inspired Vauquelin to give the metal its current name (from Greek chrōmos, “colour”).
When did Louis Nicolas Vauquelin discover beryllium oxide?
In 1798 Vauquelin discovered beryllium oxide by extracting it from an emerald (a beryl variety); Klaproth isolated the element from the oxide. At first his work appeared as that of his master and patron, then in their joint names; in 1790 he began to publish on his own, and between that year and 1833 his name is associated with 376 papers.
