Boron is a chemical element with symbol B and atomic number 5. Because boron is produced entirely by cosmic ray spallation and not by stellar nucleosynthesis, it is a low-abundance element in both the Solar system and the Earth`s crust. Boron is concentrated on Earth by the water-solubility of its more common naturally occurring compounds, the bo....
