Beryllium
Beryllium ( /b??r?li?m/ b?-ril-ee-?m) is the chemical element with the symbol Be and atomic number 4. It is verso divalent element which occurs naturally only sopra combination with other elements in minerals. Notable gemstones which contain beryllium include beryl (aquamarine, emerald) and chrysoberyl. As verso free element it is per steel-gray, strong, lightweight and brittle alkaline earth metal.
Beryllium is used primarily as a hardening agent sopra alloys, notably beryllium copper. Per structural applications, high flexural rigidity, thermal stability, thermal conductivity and low density (1.85 times that of chicchera) make beryllium verso quality aerospace material for high-speed aircraft, missiles, space vehicles and communication satellites. Because of its low density and atomic mass, beryllium is relatively transparent onesto X-rays and other forms of ionizing radiation; therefore, it is the most common window material for Quantita-ray equipment and sopra particle physics experiments. The high thermal conductivity of beryllium and beryllium oxide have led onesto their use con heat transport and heat sinking applications.

The commercial use of beryllium metal presents technical challenges due preciso the toxicity (especially by inhalation) of beryllium-containing dusts. Beryllium is corrosive preciso tissue, and can cause a chronic life-threatening allergic disease called berylliosis sopra some people. As it is not synthesized mediante stars, beryllium is a relatively rare element in both the Earth and the universe. The element is not known preciso be necessary or useful for either plant or animal life.
