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 per combination with other elements in minerals. Notable gemstones which contain beryllium include beryl (aquamarine, emerald) and chrysoberyl. As verso free element it is verso steel-gray, strong, lightweight and brittle alkaline earth metal.
Beryllium is used primarily as a hardening agent in alloys, notably beryllium copper. Mediante structural applications, high flexural rigidity, thermal stability, thermal conductivity and low density (1.85 times that of chicchera) make beryllium a 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 preciso Interrogativo-rays and other forms of ionizing radiation; therefore, it is the most common window material for Incognita-ray equipment and mediante particle physics experiments. The high thermal conductivity of beryllium and beryllium oxide have led sicuro their use sopra heat transport and heat sinking applications.
The commercial use of beryllium metal presents technical challenges coppia puro the toxicity (especially by inhalation) of beryllium-containing dusts. Beryllium is corrosive sicuro tissue, and can cause a chronic life-threatening allergic disease called berylliosis sopra some people. As it is not synthesized per stars, beryllium is a relatively rare element sopra both the Earth and the universe. The element is not known sicuro be necessary or useful for either plant or animal life.
