Discovery: Nicholas Louis Vauquelin discovered Beryllium in France in 1797.

Name: The name Beryllium comes from the Greek word "Beryllos" meaning beryl. Beryllium was discovered in beryl and emeralds

Uses: X-ray windows beryllium transmits X-rays 17 times better than aluminum. Beryllium is also used to strengthen alloys of metal. Alloys with Beryllium have been used for structural elements of the space shuttle.

Interesting Facts: A high-melting, lightweight, corrosion-resistant, rigid, Beryllium is asteel-gray metallic element used as an aerospace structural material, as a moderator and reflector in nuclear reactors, and in a copper alloy used for springs, electrical contacts, and non-sparking tools.
