Beryllium ore with a U.S. penny for scale Emerald is a naturally occurring compound of beryllium. The Sun has a concentration of 0.1 parts per billion (ppb) of beryllium. [34] Beryllium has a concentration of 2 to 6 parts per million (ppm) in the Earth's crust and is the 47th most abundant element. [35] [36] It is most concentrated in the soils ...
Beryllium-8 (8 Be, Be-8) is a radionuclide with 4 neutrons and 4 protons. It is an unbound resonance and nominally an isotope of beryllium . It decays into two alpha particles with a half-life on the order of 8.19 × 10 −17 seconds.
Klaproth discovered uranium (1789) [6] and zirconium (1789). He was also involved in the discovery or co-discovery of titanium (1795), strontium (1793), cerium (1803), and chromium (1797) and confirmed the previous discoveries of tellurium (1798) and beryllium (1798). [7] [8] Klaproth was a member and director of the Berlin Academy of Sciences. [2]
Note: René Haüy discovered that emeralds and beryls crystals are geometrically identical. He asked Vauquelin for a chemical analysis, and so Vauquelin found a new "earth" (beryllium oxide). Carl Wilhelm Scheele (1742 –1786), discovery of oxygen with Priestley; identification of molybdenum, tungsten, barium, hydrogen, and chlorine.
Friedrich Wöhler FRS(For) HonFRSE (German:; 31 July 1800 – 23 September 1882) was a German chemist known for his work in both organic and inorganic chemistry, being the first to isolate the chemical elements beryllium and yttrium in pure metallic form.
The 1980s led to the discovery of deposits of beryllium that are concentrated on the northwest corner of Round Top Mountain. [13] Throughout the 1980s, several companies held interest in the mountain, including the Cabot Corporation and the Cypus Metals Company. [12]

A graduate of California Institute of Technology, he earned his doctorate from Princeton University in 1933, and joined the Berkeley Radiation Laboratory where he discovered oxygen-15 and beryllium-10. During World War II, he worked on microwave radar at the MIT Radiation Laboratory, and then on sonar at the Navy Radio and Sound Laboratory.
