The number of electrons in each of Beryllium's shells is [2, 2] and its electron configuration is [He] 2s2. The beryllium atom has a radius of 112 pm and a Van der Waals radius of 153 pm. Beryllium is a relatively rare element in the earth's crust; it can be found in minerals such as bertrandite, chrysoberyl, phenakite, and beryl, its most common source for commercial production. Beryllium was discovered by Louis Nicolas Vauquelin in 1797 and first isolated by Friedrich Wöhler and Antoine Bussy in 1828. 
In its elemental form, beryllium has a gray metallic appearance. It is a soft
