Discovery of Beryllium

 (^) Discovered in 1797  (^) Discovered by French chemist Nicolas-Louis Vauquelin  (^) Named after beryllos , the Greek name for beryl

What makes it special?

 Beryllium has small atomic size and

ionic size than the other members of

group, also it has high ionization

enthalpy. Moreover, it forms covalent

compound while other members form

ionic compound

Chemical properties Physical properties 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 has one of the highest melting points of the light metals. It has excellent thermal conductivity, is nonmagnetic, it resists attack by concentrated nitric acid and at standard temperature and pressures beryllium resist oxidation when exposts to air.

Why is beryllium

important

 (^) Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools.  (^) Without it, we wouldn’t have many of the things we rely on each day, including cellular phones, kitchen and laundry appliances, home temperature controls, MP3 players, desktop and portable computers, and your car.
