4Group- Metals, Nonmetals, Metalloids? Beryllium is a metalFound in group 2It is Alkali-Earth Metal
5History Discovered by Louis-Nicholas Vauquelin in 1798 Etymological origin of name: Greek: beryllos, berylElement symbol comes from the first two letters of the element!
6Compounds Where it Commonly Exists One compound is Beryllium dihydride (BeH2). It appers as a solid ,and it is white. It’s density is 650 kg m-3.Another compound is Beryllium Oxide (BeO3). It is a crystalline solid. It’s density is 3010 kg m-3.Beryllium Oxide
7UsesBeryllium, unlike other metals, is virtually transparent to x-rays. So, it is used in radiation windows for x-ray tubes.Beryllium alloys are also used for aircraft, satellites and spacecraft because they require light-weight materials.Another use of Beryllium is that it used in nuclear reactors.
8FoundBeryllium is not found pure in nature, but beryllium compounds can be found in different mineral rocks, soil, coal, oil, and volcanic dust.
9Where is it found?Can be found almost anywhere in the world, but it is not found in its pure form. Found in Emeralds and other gems. It is natural.
