Boron - Wikipedia

2020-8-15 · Boron is a chemical element with the syol B and atomic nuer 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in the Solar System and in the Earth''s crust. It constitutes about 0.001 percent by weight of Earth’s crust. Boron is concentrated on Earth by the water-solubility of its more common naturally occurring
