Boron properties
Boron is part of the elements called metalloids or semi-metals. These types of elements have intermediate properties between metals and nonmetals. As for its electrical conductivity, this type of materials to which boron belongs, are semiconductors.
The state of boron in its natural form is solid (non-magnetic). Boron is a black-looking chemical element and belongs to the group of metalloids. The atomic number of boron is 5. The chemical symbol for boron is B. The melting point of boron is 2349 degrees Kelvin, or 2076.85 degrees Celsius or degrees Celsius. The boiling point of boron is 4200 degrees Kelvin or 3927.85 degrees Celsius or degrees Celsius.
Uses of boron
Boron is a chemical element that has been used for thousands of years. If you have ever wondered what boron is for , here is a list of its possible uses:
- A large amount of boron is used in conjunction with sodium tetraborate to insulate fiberglass. It is also used in many detergent and bleach cleaning products.
- Most of the boron is used to produce glass and ceramics. Borosilicate glass has exceptional resistance to thermal shock (sudden temperature changes that cause the glass to break).
- Boron filaments are used as lightweight but highly resistant materials in the creation of aerospace structures. It is also used to produce some of golf clubs and fishing rods.
- Boron carbide protections can be used as control barriers in nuclear reactors. This prevents a nuclear reactor from spinning out of control. Boron carbide is also used in bulletproof vests and tank armor.
- Metal borides are very strong and are often applied to a substance to increase its hardness.
- Boron is a part of neodymium magnets , the strongest type of permanent magnet. These magnets are used in magnetic resonance imaging machines, CD and DVD players, mobile phones, timers, and more.
- Boric acid is sometimes used as an insecticide against ants, fleas, and roaches.
- Sodium borate can be used as a combustion retardant in plastics and rubber.
Boron Atomic Properties
The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. As for the position where to find boron within the periodic table of the elements, boron is in group 13 and period 2. Boron has an atomic mass of 10,811 u.
The electronic configuration for boron is [He] 2s22p1. The electronic configuration of the elements, determines the form in which the electrons are structured in the atoms of an element. The average radius of boron is 85 pm, its atomic radius or Bohr radius is 87 pm, and its covalent radius is 82 pm. Boron has a total of 5 electrons whose distribution is as follows: In the first layer it has 2 electrons and in the second it has 3 electrons.
