Model Planetari Bohr Berilium (Be)
Rajah Dot Lewis Berilium (Be)
Description
Hard, brittle, steel-gray metal. Lightest rigid metal. Formerly called glucinium (Gl) for its sweet but deadly taste.
Uses
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.
Sources
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.
Pronounciation (English)
beh-RIL-i-em
