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