- found: Beryllium element facts, via Chemicool website, Oct. 26, 2012 (Beryllium is an alkali earth metal; Vauquelin proposed that beryllia contained a previously undiscovered element, an earth metal. He initially called this new element 'earth of beryl.' The sweet taste of the salts then led to the new element being renamed 'glyceynum,' then 'glucina' or 'glucine.' Pure beryllium was first isolated from its salts in 1828 by Friederich Wöhler in Germany and, independently, Antoine Bussy in France. Wöhler was unhappy with the name the new element had been given, preferring beryllium from the Greek word 'beryllos,' meaning the mineral beryl. Wöhler's countryman, Martin Klaproth, had already pointed out in 1801 that yttria also forms sweet salts. A name derived from 'beryllos' would be less likely to cause confusion than one derived from 'glykis.' Klaproth also noted that a genus of plants was already called glucine. Bussy, however, preferred to call the new element 'glucinium.' Finally, in 1949, IUPAC chose beryllium as the element's name and this decision became official in 1957)
