- Beryllium is an element with the atomic number 4 in the periodic table.
- It is a bivalent and highly toxic element.
- The element has one of the highest melting points among the light metals.
- Beryllium exists in 30 different minerals, among which bertrandite, beryl, chrysoberyl, and phenacite are the most important.
- Beryllium is used as an alloying agent.
- It possesses high strength, non-magnetic properties, better resistance, and dimensionally stable over a significant range of temperature.
- Beryllium fused with copper forms alloys which are used in defense and aerospace industries is a typical application of Beryllium.
- It is nonmagnetic, holds excellent thermal conductivity and resists attack by concentrated nitric acid.
- Beryllium resists oxidation when exposed to air at standard temperature and pressure.
- It is found in 30 different minerals of which bertrandite, phenakite, and Beryl are the most important.
- Beryllium content in the ground can pass into the plants grown on it when it is in a soluble form.
- Aquamarine and emerald are the most precious forms of beryl. Beryl is the mineral form of beryllium aluminum cyclosilicate.
- X-ray detection diagnostic uses of Beryllium as it could pass through latter.
