Antoine Bussy – isolated beryllium element

Biography & contributions


Antoine Bussy [Antoine Alexandre Brutus Bussy] , a French chemist born on May 29, 1794 – died on February 01, 1882. Antoine was famous for well known studies in the field of chemistry, biochemistry and also credited with beryllium element isolation.


Antoine Bussy along with another eminent chemist Friedrich Wohler independently isolated beryllium by the chemical reaction of metallic potassium with beryllium chloride


BeCl2 + 2K → 2 KCl + Be


Antoine isolated and identified modern industrial red dye called alizarin, codeine and also isolated the first amino-acid asparagin.


Antoine Bussy published the article called 'Memoire sur le Radical metallique de la Magnesie' where he described magnesium preparation.


Facts about beryllium

Beryllium symbol is Be which is fourth element of the periodic table and was discovered and named in 1798 by a chemist named Vaquelin. He actually found the element when he was working with emeralds. Beryllium is in emeralds. It is also in another gem called aquamarine. Beryllium is only one of many elements inside an emerald.


Beryllium could be produced by reducing beryllium compounds such as beryllium chloride with metallic potassium or sodium. Currently most beryllium is produced by reducing beryllium fluoride with purified magnesium.


Beryllium is a very light metal. It is also used with other metals to make strong pieces for machines. Beryllium is often used in springs, satellites, space shuttles. Beryllium is most commonly extracted from the mineral beryl, which is either sintered using an extraction agent or melted into a soluble mixture.


Beryllium improves many physical properties when added as an alloying element to aluminium, copper, iron and nickel.


Beryllium is a steel gray and hard metal that is brittle at room temperature and has a close-packed hexagonal crystal structure. Beryllium releases neutrons under bombardment by gamma rays.


Beryllium is also commonly used in some neutron sources in laboratory devices in which relatively few neutrons are needed. Beryllium is also used in fuel fabrication for CANDU fuel bundles, Joint European Torus nuclear-fusion research laboratory, as a cladding material for nuclear fuel rods.


Beryllium's chemical behavior is largely a result of its small atomic and ionic radii. It thus has very high ionization potentials and strong polarization while bonded to other atoms, which is why all of its compounds are covalent.


It is more chemically similar to aluminium than its close neighbors in the periodic table due to having a similar charge-to-radius ratio. Beryllium dissolves readily in non-oxidizing acids, such as HCl and diluted H2SO4, but not in nitric acid or water as this forms the oxide.


Facts about alizarin


Alizarin is obtained from the root of the common madder plant, Rubia tinctorum. Alizarin is the main ingredient for the manufacture of the madder lake pigments known to painters as Rose madder and Alizarin crimson. Alizarin in the most common usage of the term has a deep red color.


Alizarin is one of ten dihydroxyanthraquinone isomers. Its molecular structure can be viewed as being derived from anthraquinone by replacement of two neighboring hydrogen atoms (H) by hydroxyl groups (-OH).


Alizarin Red is used in a biochemical assay to determine, quantitatively by colorimetry, the presence of calcific deposition by cells of an osteogenic lineage.


Facts about asparagin


Asparagine is the amide of aspartic acid. It has carboxamide as the side-chain's functional group. Asparagine is found on the surface as well as buried within proteins. Asparagine is a common site for attachment of carbohydrates in glycoproteins in certain biological pathways.
