Cyclosilicates have closed cycles made of SiO 4 tetrahedrons in their structure: in the case of beryl, cycles made of six SiO 4 tetrahedrons. These cycles are stacked on each other and result in channels inside the structure.

WebBeryllium has a wide variety of applications, including the manufacture of electrical equipment, nuclear reactors, electronic components and aerospace components. The beryllium extracted from beryl crystals at the Triple Chance mine, Broken Hill were used by NASA for the Apollo Space Program. History WebLithium is rare in the Universe, although it was one of the three elements, along with hydrogen and helium, to be created in the Big Bang. The element was discovered on Earth in 1817 by Johan August Arfvedson (1792-1841) in Stockholm when he investigated petalite, one of the first lithium minerals to be discovered.
WebBeryl minerals are made of beryllium aluminum silicate: Be 3 Al 2 (Si 6 O 18 ). They form in granite pegmatite rocks and hydrothermal carbonate veins and cavities, where hydrothermal processes have modified the granitic composition. Beryls can also be found in gem-gravel placer (alluvial) deposits. Web33K views 3 years ago In this video we will write the electron configuration for Be 2+, the Beryllium ion.
