  Beryllium (Be) - The Chemical Elements

  202048 · Due to the sweetness of the beryllium salts, this chemical element used to be labeled as glucinum or glucinium, a term derived from the Greek word ‘glykys’ denoting ‘sweet’. This name was kept until 1949, when IUPAC chose the present name beryllium, given after the Greek term for the mineral beryl – ‘beryllos’.
