Beryllium

Although emeralds and beryl were known to ancient civilizations, they were first recognized as the same mineral by Abbe Hauy in 1798. Later that year, Louis-Nicholas Vauquelin, a French chemist, discovered that an unknown element was present in emeralds and beryl. Attempts to isolate the new element finally succeeded in 1828 when two chemists, Friedrich Wolhler of Germany and A. Bussy of France, independently produced beryllium by reducing beryllium chloride (BeCl2) with potassium in a platinum crucible. Today, beryllium is primarily obtained from the minerals beryl and extradite through a chemical process or through the electrolysis of a mixture of molten beryllium chloride and sodium chloride(http://pearl1.lanl.gov/periodic/ ).

Beryllium’s atomic number is 4 and it‘s element symbol is Be. The color of it is steel gray. It’s atomic weight is 9.012182. The melting point is 1560 K. It’s boiling point is 2744 K. The density of it is 1.85 grams per cubic centimeter. It’s phase at room temperature is solid and it’s element classification is a metal. Both it’s period and group number is 2.The name of the group that it belongs to is the alkaline earth metals. Beryllium comes from the Greek word beryl which is a type of mineral. It is

The uptake of beryllium has consequences mainly for human health.

Beryllium’s estimated crystal abundance is 2. It was once known as glucinum, which means sweet, since beryllium and many of its compounds have a sugary taste. Other beryllium alloys are used in the windshield, brake disks and other structural components of the space shuttle. It will not be accumulated in the bodies of fish. People who live near hazardous landfill sites that contain high concentrations of beryllium may also be exposed to higher than normal levels of beryllium. Some people that suffer from CBD will develop anorexia and blueness of hands and feet. It can be treated, but it cannot be cured(beryllium411. CBD is primarily a lung disease, but it may also affect the lymph nodes, skin, spleen, liver, kidneys, and heart.

Beryllium can also cause allergic reactions with people that are hypersensitive to this chemical. 323 eV and it’s oxidation state is +2(http://pearl1.

Owing to its unique physical properties, beryllium is used in a variety of high-technology industries, and CBD continues to be an important public health concern.
