    What is Boron

    Boron is classified as a metalloid, and chemically it is an element. Metalloids are elements that show properties of both metals and non-metals. The density of boron is 2.37 grams per cubic centimeter. Boron has the symbol B, atomic number 5, and atomic mass 10.811 amu. Boron's atom has 5 electrons, 5 protons, 6 neutrons and 2 energy levels. In the Periodic Table, Boron is located in Group 13, Period 2 and Block P. Boron is found in the solid state at room temperature, its melting point is 2075 °C (3767 °F), and its boiling point is 4000 °C (7232 °F).

    Boron was discovered by the French chemists Joseph-Louis Gay-Lussac and Louis-Jacques Thenard and the English chemist Sir Humphry Davy in 1808.

    Properties of Boron

    • Boron is found in two forms (Allotropes), Amorphous Boron and Crystalline Boron.
    • Amorphous boron has molecules linked together randomly, so it is found in the form of powder, its color is dark brown.
    • Crystalline Boron is a black colored crystalline material which is extremely hard and brittle.
    • Crystalline boron is chemically almost inert as compared to amorphous boron.
    • When exposed to oxygen in the air, a thin layer of boron trioxide (B2O3) is formed over the boron, which prevents further reaction with oxygen.
    • Boron does not normally react with acids, but it reacts with hot nitric acid (HNO3) and hot sulfuric acid (H2SO4).
    • Boron dissolves in molten metals.
    • Boron is a poor conductor of electricity at room temperature, whereas at high temperatures boron is a good conductor of electricity like the metals.
    • Boron is chemically less reactive, but it is not found in pure state in nature.

    Uses of Boron

    • Boron is used to give green light in firecrackers.
    • Boron is used in the production of ceramics and borosilicate glasses, which are hard and heat resistant. It is also used in the manufacture of fiberglass.
    • Amorphous boron is used as a rocket fuel igniter.
    • The isotope of boron, boron-10, has the ability to absorb neutrons, so it is used in nuclear reactors.
    • Boron-10 is also used in neutron detection equipment.
    • Boric acid, borax, and boric oxide are compounds of boron that are used in eye drops, washing powders, and mild antiseptics.
    • Borax is also used in food preservation.
    • Boron filament is used in the aerospace industry because it is light in weight and extremely strong.
    • Boron, iron and niobidium alloys are used to make very powerful magnets.
    • Boron is used in the manufacture of semiconductors.

    Interesting facts about Boron

    • Boron is the 37th most abundant element in the Earth's crust.
    • We get about 2 mg of boron daily through food, and about 18 mg of boron is present in our body.
    • Boron is an essential nutrient for plants.
    • Possibilities of treatment of Arthritis with Boron are being explored by the scientists.
