Introduction

At first sight, boron looks like an ordinary piece of brown rock. But if you look closer, you would notice that it has no smell. If you throw it, you would not be able to break it. If you found it, you must have been lucky because it is rare. So what is this element? Read the bullet points below and my information sheet to find out.

History

  • Boron was discovered by Joseph Luis, Gay-Luissoc, Louis Jaques Thénard, and Humphy Davy in 1808.
  • The scientists discovered boron by combining boric acid with potassium. Today, scientists make born by heating borax with carbon.
  • The name boron is based on the arabic word buraq. It's atomic symbol is the letter "B" with an atomic number 5 over it, and its atomic mass below.
  • Boron is rare to find though; it mostly comes from outer space and in big mines in certain countries.

Physical Properties

  • Boron looks like a rock. It is solid at room temperature.
  • Boron is a metalloid.
  • It's atomic number is 5. It's atomic mass is 10.81.
  • It has no smell and it is almost as hard as diamonds.
  • Boron also is hard to melt, it has a melting point of 2077 C and a boiling point of 4000 C. (Please don't try this at home!)

Industrial and Medicinal Uses

  • Boron is used in products such as borax, washing powder, cleaning compounds, tile glazes, detergents and soaps.
  • It is also used in glass and ceramics, and enamels covering the steel of refrigerators. So we use boron all the time and we do not even realize it.
  • In addition to the uses above, boron also has industrial uses, one of which is a rocket fuel, which gives the jet flame a green color. It can also help make resistant glass since it is almost as hard as diamond.
  • Boron can also help regulate nuclear reactors. This is important because if you do not regulate them, they have a chance of exploding.
  • Boron is also is used to detect neutorons. It is also used to give steel extra hardness.
  • Boron can help you medicinally, too.
  • It is used in: eye drops and mild antiseptics.
  • Boron boosts bone density and prevents arthritis. This is important because a rock is almost never used as a medical product.
  • Boron is toxic if taken in large amounts though. And it is highly flammable, so do not burn your medication!

Three Interesting Facts

  • There are three main boron deposits: in the US. Russia and Turkey.
  • Boron makes up only 0.001% of the earth's crust.
  • The largest boron mine in the world is located in Boron, California in the Mohave Desert.
