Beryllium

berylliumburr-ill-ee-um

beryllium has an atomic number of 4 atomic mass: 9.0122mass# is 9

it's symbol is Be

the origin of the name is from the greek word bellos meaning the mineral beryl. it is a steel gray metal resistant to attack by concentrated nitric acid.

at room temp. it is a solid.its melting point is 2,348.6 degrees farenheitits boiling point is at 4,479.8 F

according to the beryllium science and technology association, beryllium-containing materials are used in cell-phones, cameras, and other portable devices.

beryllium is transparent to x-rays, and so it it is used in radiation windows for x-ray tubes.beryllium is used as an alloy with copper to make spark proof tools.

cost, pure: $748/100gcost, bulk: $93/100gberyllium alloys are used in the aerospace industry as lightweight materials for highperformance aircraft,sattelites, and spacecraft

beryllium is also used in nuclear reactors as a reflector and absorber of neutrons, a sheild and a moterator.beryllium is the lightest member of the alkine earth metals faminly, that includes beryllium, magnesium, calcium, strontium, barium, and radium.

beryllium is a very toxic metal. it is esspecially dangerous in powder form. the effects af inhaling beryllium powder can be acute, or chronic either the effects happen very quickly, or over a period of time.

acute effects would include pnemonia-like symptoms that can result in death in a short time. chronic effects would be desises of the respitory system, such as bronchitis, and lung cancer

density is 1.8477grams/cubic cm.-found in paris,france - does not corrode (rust)-it stronger than steel, yet is the lightest metal-its compounds are very sweet tasting but are very toxic

-it transmits x-rays 17 times faster than aluminum. common uses:-gyroscopes-computer parts (shutters)-aircrafts-missiles-ceramics

it has 1.2 electrons per shellit was discovered in 1798it was discovered by louis nicolas vauquelindensity is 1.8477grams/cubic cm.

A world without beryllium would be a place very different from the world that we know today. For example, copper beryllium materials played an unforgettable role in capping of theMacondo Well in the Gulf of Mexico oil spill disaster. Clamps that allowed the capping stack tobe securely fastened to the damaged well pipe were made of copper beryllium due to thematerial’s incredible strength, resistance to stress and ability to slip over other materials without galling. In addition, only copper beryllium has the strength, flexibility and transparency tomagnetic fields that allowed the sensitive equipment to locate the blown out well and determine the precise location of the drill bit. So beryllium is a very important role in our world today.

Beryllium reacts with acids and with water to form hydrogen gas. It reacts briefly with oxygen in the air to form beryllium oxide (BeO). The beryllium oxide forms a thin skin on the surface of the metal that prevents the metal from reacting further with oxygen.

beryllium has 0.00019% abundance in the earths crust
