Boron is a chemical element with symbol B and atomic number 5. Because boron is produced entirely by cosmic ray spallation‚ it is a low-abundance element in both the solar system and the Earth’s. Chemically uncombined boron‚ which is classified as a metalloid‚ is not found naturally on Earth. Industrially‚ very pure boron is produced extremely difficult. Several types of boron exist: amorphous boron is a brown powder and crystalline boron is black and extremely hard. Boron compounds are used in
