Beryllium was discovered by Louis-Nicolas Vauquelin in 1798 as acomponent of beryl and in emeralds. Beryllium is considered a carcinogen, meaning that it can cause cancer in humans. Aluminum beryllium components helped protect the rovers on their landings, and then served again to unfold their drive-off ramps. It has high thermal conductivity and is nonmagnetic It is used as components for missiles and rockets. Beryllium was discovered by French pharmacist Louis Nicolas Vanquelin in 1798.
Beryllium is a silvery-white, lustrous, relatively soft metal of group 2 of the periodic table.

Today, beryllium is primarily obtained from the minerals beryl Be 3Al 2 SiO 3 6 and bertrandite 4BeO·2SiO 2·H 2O through a chemical process or through the electrolysis of a mixture of molten beryllium chloride BeCl 2 and sodium chloride NaCl. Their beautiful green colour is due to traces of chromium.
He observed that it then emitted a new kind of subatomic particle which had mass but no charge. Beryllium's chemical similarityto aluminium was probably why beryllium was missed in previoussearches. As one of the lightest of all metals, it has one of the highest melting points of the light metals. Beryllium oxide BeO , a compound of beryllium, is used in the nuclear industry and in ceramics. This neutral particle was the neutron. Beryllium metal did not become readily available to industry until 1957. Its cosmic abundance is 20 on the scale in which , the standard, is 1,000,000.
Beryllium components also fly in the Spitzer Space Telescope. Beryllium is also used in nuclear reactors as a reflector and absorber of neutrons, a shield and a moderator. . He determined that this new metal was a component of beryl and emeralds. Total world production per year is around 364 tons.
It was found in emeralds from the mountains of France and California. It can withstand great heat and is ideal for spacecraft, missiles, and nuclear weapons. Using a biology-first, target-centric approach, Beryllium has developed deep expertise in protein engineering, expression and purification, as well as functional biology and protein structure designed to find unique therapeutic drugs. When copper and nickel are alloyed with beryllium they not only become much better at conducting electricity and heat, but they display remarkable elasticity. The only naturally occurring is the stable beryllium-9, although 11 other isotopes are known. Beryllium is used as an alloying agent in the production of beryllium-copper. Pure beryllium may be obtained by electrolysis of molten BeCl 2 containing some NaCl.
Beryllium is used as an alloy with copper to make spark-proof tools. Analysis of the oxygen in these gems enables their source to be identified because the isotope ratio of oxygen-18 to oxygen-16 varies according to where the mineral is found. Beryllium oxide called beryllia is known for its high heat capacity and is an important component of certain sensitive electronic equipment. In terms weight vs strength it is harder than diamond. Unfortunately for the chemists that discovered this particular property, beryllium and many of its compounds are poisonous and should never be tasted or ingested. The forms of beryl, emerald and , have a closely approaching that given above, but industrial ores contain less beryllium; most beryl is obtained as a by-product of other mining operations, with the larger crystals being picked out by hand.
Beryllium is alloyed with 2% beryllium, 98% copper to form a wear resistant material, known as beryllium bronze, used in gyroscopes and other devices where wear resistance is important. Beryllium has no known biological role, and its dust causes chronic inflammation of the lungs and shortage of breath. Beryllium chloride BeCl 2 catalyzes the Friedel-Crafts reaction and is used in cell baths for electrowinning or electrorefining beryllium. Louis Nicolas Vauquelin also discovered the element chromium. Non-magnetic metals are very useful in electronics.
This name is derived from the sweetish taste of many of its compounds. Discovered by: Nicholas Louis Vauquelin. It resists attack by concentrated nitric acid, has excellent thermal conductivity, and is nonmagnetic. The salt is added since the molten BeCl 2 conducts very poorly. However, powdered be … ryllium metal does burn in air to give a mixture of white beryllium oxide, BeO, and beryllium nitride, Be 3 N 2.
