What are Boron features?

Boron is a chemical element with an atomic number of five and atomic symbol B. Remarkable Boron properties include its efficiency in capturing neutrons and subsequent efficiency of one of its isotopes as a radiation shield; its extreme hardness, tensile strength and hardness of several pine compounds; and the existence of several borons and polymorphs. It is a metaloid with a standard atomic weight of 10.811. It is fixed at a room temperature, with a melting point of 3769 ° F (2349 ° K) and boiling point 7101 ° F (4200 ° K) at atmospheric pressure.

The physical properties of the boron depends on the allotropy are different configurations of the same element, with the atoms of the element joining together in different ways. Boron's main allotrops are called crystalline Boron and Amorphic Boor. The amorphous boron, which is made of boron icosahedral crystals, was randomly connected without a major structure, is a shape powder.

The crystalline boor is black and very hard. Is diamagentic; In the presence of a magnetic field, it creates its own magnetic field that hasresulting a repellent effect. Crystalline boor can be arranged in four different main crystalline structures called polymorphs. Starting with a pressure of approximately £ 23.206,000 per square inch (about 160 Gigapascals), Boron's properties and become a superconductor.

Boron Farms primarily covalent chemical bonds and can form a stable molecular network. He is a member of the aluminum family, but the properties of Bor are actually closer to silicon than aluminum. Boron is most common in nature in a composite tetra -based decahydrate of sodium, also known as Borax. Bur carbide and boron cubic nitride are among the most difficult materials. Boron is essential for plant life biochemistry and ultra -topic quantities are also used in animals.

Boron has 13 well -known isotopes, two of which, 10 b and 11 b, are stable. About 80 percent of all naturally occurring Boron is ^{11 B, with the rest of which is 10 b. Another nine known isotopes are short -term, with a half -life of milliseconds or even less.}

Boron properties give the element and its compound a number of uses. The power of Boron is valuable in the aviation industry. Boron carbide and boron cubic nitride are useful as industrial abrasives due to their extreme hardness and Boron carbide is also integrated into modern bulletproof vests and armored vehicles. Semiconductors made of fabrics such as silicon, silicon carbide and Germanium are doped with Boron. The isotop Borona 10

b is used in control rods and emergency shut -off systems Nuclreactors protect and are experimented for use in the form of radiotherapy called boron neutrons therapy to treat head, neck and brain cancer.
