Health Consultation: A Note of Explanation

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.

Thermal Conductivity of Metals, Metallic Elements and Alloys

Sources of Beryllium. Beryllium is the first member of the alkaline earth family of elements, which means that it's highly reactive and easily bonds to form compounds but is difficult to separate into a pure metal. Beryllium was discovered by Louis-Nicolas Vauquelin in 1798 as a component of beryl and in emeralds.
