B - Boron - METALLOIDS
Boron is a chemical element with symbol B and atomic number 5. It is classified as a transition metal and is found in the second period of the periodic table of elements. Boron is metallic white and slightly shiny. It is almost tasteless and odorless. Boron is very hard and very difficult to work and mold, so it is often combined with other metals to facilitate its processing.
Boron is one of four elements that can form very strong covalent bonds with another boron atom. This property makes it an excellent addition to materials such as alloys and metals. Boron is also used as an alloying element to improve corrosion and abrasion resistance.
Boron is also used in many industries. It is used to make batteries, tools, insulation materials, abrasive products, motors, gears and mechanical parts. Boron is also used in the production of high quality lubricants and greases, as well as in the manufacture of chemicals, dyes and drugs.
Finally, boron is also used as a fertilizer because it is highly concentrated in trace elements and nutrient salts. It is also used for soil enrichment and as an addition to fertilizer to improve agricultural productivity.
