Noun
1. boron (B)​
Wikipedia definition
2. Boron​Boron is the chemical element with atomic number 5 and the chemical symbol B. 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. However, boron is concentrated on Earth by the water-solubility of its more common naturally occurring compounds, the borate minerals. These are mined industrially as evaporate ores, such as borax and kernite.
