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 hard, grayish metal naturally found in mineral rocks, coal, soil, and volcanic dust. Beryllium compounds are commercially mined, and the Beryllium is purified for use in nuclear weapons and reactors, aircraft and space vehicle structures, instruments, x-ray …

2025年1月31日 · beryllium (Be), chemical element, the lightest member of the alkaline-earth metals of Group 2 (IIa) of the periodic table, used in metallurgy as a hardening agent and in many outer space and nuclear applications.

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.
