Beryllium is a chemical element; it has symbol Be and atomic number 4. It is a steel-gray, hard, strong, lightweight and brittle alkaline earth metal. It is a divalent element that occurs naturally only in combination with other elements to form minerals. Gemstones high in beryllium include beryl (aquamarine, emerald, red beryl) and chrysoberyl.

Beryllium is a silvery-white, lustrous, relatively soft metal of group 2 of the periodic table. The metal is unaffected by air or water, even at red heat. When copper and nickel are alloyed with beryllium they not only become much better at conducting electricity and heat, but they display remarkable elasticity.

Beryllium is the 4th element in the periodic table and has a symbol of Be and atomic number of 4. It has an atomic weight of 9.01218 and a mass number of 9. Beryllium has four protons and five neutrons in its nucleus, and four electrons in two shells.
