Other beryllium alloys are used in the windshield, brake disks and other structural components of the space shuttle. Beryllium oxide (BeO), a compound of beryllium, is used in the nuclear industry and in ceramics. Beryllium was once known as glucinum, which means sweet, since beryllium and many of its compounds have a sugary taste. Beryllium forms 4-coordinated complex ions. Some simple background. Although beryllium doesn't normally form simple ions, Be 2+, it does form ions in these, the beryllium ion becomes attached to four water molecules to give a complex ion with the formula [Be(H 2 O) 4] 2+.. The ion is said to be 4-coordinated, or to have a coordination number of 4, because there are four water.

  Beryllium is an element that occurs naturally. It is present in a variety of materials, such as rocks, coal and oil, soil, and volcanic dust. Two kinds of mineral rocks, bertrandite and beryl, are mined commercially for the recovery of beryllium. Very pure gem™quality beryl is better known as either aquamarine (blue or blue-green) or emerald (green). List of Beryllium Compounds, Common Compounds of Beryllium Be, Formula, Molecular Weight.

Beryllium is a lightweight but extremely strong metal used in the aerospace, electronics, energy, telecommunications, medical, and defense industries. Beryllium-copper alloys are widely used because of their electrical and thermal conductivity, hardness, and good corrosion resistance.

Marek Jakubowski, Cezary PałczyŃski, in Handbook on the Toxicology of Metals (Fourth Edition), Soil, Water, and Air. Beryllium is the 44th most abundant element in the Earth’s crust. The average beryllium concentration in the Earth’s crust is estimated to be mg/kg.

Approximately 50 beryllium minerals occur in nature, and over half of these are silicates. For an alternative listing please see Inorganic compounds of Beryllium. Subcategories.

Pure beryllium is a hard gray metal that does not occur naturally but does occur as a chemical component of certain kinds of rocks, coal and oil, soil, and volcanic dust.

PH) Compiled by Norman L. Durocher Litton Systems, Inc. Environmental Systems Division Pearl Street Bethesda, Maryland. Beryllium and its compounds were classified as carcinogenic in man both by the ACGIH and the International Agency for Research on Cancer (IARC).

In beryllium and its inorganic compounds were classified as carcinogenic in man also by the DFG Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area (Greim ).

The high toxicity of beryllium compounds, 4–6 together with the air sensitive nature of organometallic derivatives, have limited study in this promising area of chemistry. Much of the experimental development of an understanding of this area is due to work by Coates and co-workers between and at Durham and Wyoming.

Beryllium forms such remarkable alloys that it is used in "jets, gyroscopes, and jewelry, as well as in cameras, cell phones, golf clubs, watches, space telescopes, X-ray systems, trumpets and flutes, and nuclear reactors." This is an interesting book on an element that is unfamiliar to most of us.4/4(1).

The oxidation number of beryllium in beryllia is Synthesis. Beryllium oxide is made through the calcination (heating) of beryllium hydroxide. Be(OH) 2 (s) (°C) → BeO(s) + H 2 O(l) It can also be made by the oxidation of beryllium metal.

Beryllium, chemical element that is the lightest member of the alkaline-earth metals of Group 2 of the periodic table. It is used in metallurgy as a hardening agent and in many outer space and nuclear applications.

It is a steel-gray metal that is quite brittle at room temperature. Beryllium and beryllium compounds were first listed in the Second Report on Carcinogens as. reasonably anticipated to be human carcinogens. At ordinary temperatures, beryllium resists oxidation in air; however, its ability to scratch glass is probably due to the formation of a thin layer of the Size: 5MB.InWohler’s name “beryllium” was officially recognized by IUPAC (Ballance et al., ).
