For the quintessence of classical philosophy, see Aether (classical element). Boron is a chemical element with symbol B and atomic number 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.
History and Uses: Boron was discovered by Joseph-Louis Gay-Lussac and Louis-Jaques ThÃ©nard, French chemists, and independently by Sir Humphry Davy, an English chemist, in 1808. They all isolated boron by combining boric acid (H3BO3) with potassium.
