Chemical

Properties and

Characteristics of Beryllium

Beryllium is a hard, silver-gray metal that sits beneath magnesium in the periodic table. Like all other elements, beryllium has isotopes, but its most stable and common form is beryllium-9.

It has a low density of 1.85 g/cm cubed, and its atomic mass is approximately 9.012 g/mol. Beryllium has a high melting point of 1560 and a boiling point of 2742.

It is diamagnetic, and its heat capacity is high, at around 1.825 J/gK. In terms of chemical reactivity, beryllium is highly resistant to oxidation and corrosion.

It reacts readily with non-metals such as oxygen, halogens, and sulfur to form binary compounds. Beryllium also reacts with acid, especially sulfuric acid, to form soluble salts and hydrogen gas.

Occurrence and Mining of Beryllium

Beryllium occurs in minerals such as beryl and bertrandite. Beryl, the most important beryllium mineral, is a beryllium aluminum silicate that usually contains other elements such as iron, magnesium, and chromium.

Bertrandite, on the other hand, is a beryllium silicate that is commonly found in the United States, specifically Utah. The mining of beryllium is a complex process due to the rarity and cost of the element.

Beryllium minerals are typically found in metamorphic and igneous rocks. The process of extracting beryllium from its ore involves crushing and grinding the rock into a fine powder.

The powder is then treated with sulfuric acid to break down the minerals and release the beryllium. The beryllium is then extracted using a mixture of ammonium hydroxide and water.

History and Discovery of Beryllium

Beryllium was first discovered by Louis Nicolas Vauquelin, a French chemist, in 1798. He discovered it as an oxide of a brightly colored mineral called beryl.

Two years later, a Swedish chemist named Axel Fredrik Cronstedt discovered the element in another mineral, which he named gadolinite. However, both Vauquelin and Cronstedt had not identified the element accurately, and it wasn’t till 1828 when two French chemists, Antoine Bussy and Friedrich Whler, independently produced pure beryllium metal in their laboratories.

During the 1800s, beryllium was known as “glucinum” or “glaucinium” because of its vibrant yellow-green color in some of its minerals. It wasn’t until the early 20th century that the name beryllium was coined, derived from the Greek word “beryllos,” meaning crystal.

Properties and

Characteristics of Beryllium

Beryllium has a range of fascinating properties and characteristics that make it a sought-after element in a wide range of industries. Due to its low density and high stiffness, it’s used extensively in the manufacturing and construction of lightweight materials, such as alloys that are both corrosion-resistant and high-strength.

One of the unique properties of beryllium is its low atomic number, which gives it a low electron density. This property makes beryllium transparent to X-rays, a characteristic that has found applications in the production of X-ray windows, radiation detectors, and other medical and scientific imaging equipment.

The chemical properties of beryllium are also of interest to scientists. Beryllium is highly flammable, and its oxide is a powerful oxidizer.

When exposed to air, it burns with a bright white flame, producing a mixture of beryllium oxide and beryllium nitride. Beryllium displays multiple oxidation states, but its most common states are +2 and +1.

Conclusion

In conclusion, beryllium is a fascinating element with exceptional properties and characteristics. It’s nearly as hard as a diamond, highly refractory, and has a quite low atomic number, which enables it to be transparent to X-rays.
