4Be Beryllium

Description

Named for the gemstone beryl, of which it is a component. Beryllium is a soft, silvery-white, shiny metal. It is very light and has a high melting point, so it is desirable for use in metal alloys. It is used in alloys with nickel and copper as a light-weight structural material. Beryllium has a very high elasticity, consequently it is often used for gears and springs and other elastic devices. It is transparent to X-rays, so it often is used to make windows in X-ray tubes. Compounds of beryllium are very poisonous. Even dust of the powdered metal or its oxide may cause very serious illness when inhaled.
