Lightest rigid metal. Formerly called glucinium (Gl) for its sweet but deadly taste. Its ability to absorb large amounts of heat makes it useful in spacecraft, missiles, aircraft, etc. Emeralds are beryl crystals with chromium traces giving them their green color. Found mostly in minerals like beryl [AlBe3(Si6O18)] and chrysoberyl (Al2BeO4). Pure beryllium is obtained by chemically reducing beryl mineral. Also by electrolysis of beryllium chloride. qy8JyQShZRA Beryllium
Nobelium was discovered by Albert Ghiorso, Glenn T. Seaborg, John R. Walton and Torbjørn Sikkeland in 1958 at the University of California, Berkeley.

It was produced by the bombardment of curium with carbon atoms.

It was correctly identified in 1966 by scientists at the Flerov Laboratory of Nuclear Reactions in Dubna, Soviet Union. Named after of Alfred Nobel, Swedish chemist who discovered dynamite and founder of the Nobel Prizes 4 1797 Nicholas Louis Vauquelin France From the Greek word "beryllos" meaning "beryl"
