Compounds Where it Commonly ExistsOne 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

UsesBeryllium, 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.

Found Beryllium is not

found pure in nature, but beryllium compounds can be found in different mineral rocks, soil, coal, oil, and volcanic dust.

Where 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.
