Boron is a chemical element. It is a metalloid. Its chemical symbol is B and its atomic number is 5. It was first discovered in 1808 by the efforts of French physicist Joseph-Louis Gay-Lussac, French chemist Louis-Jaques Thenard. They reacted sodium with boric acid to separate boron element. Later it was isolated by British chemist Sir Humphry Davy independently.
These early uses echo in borax's (and ultimately, boron's) name: The word is from the Arabic buraq, or white. However, the element itself was not extracted until 1808, according to the Royal Society of Chemistry. Even then, chemists weren't able to get a pure form of boron. That goal was not reached until a century later, in 1909, when U.S. chemist Ezekiel Weintraub isolated 99 percent pure boron.
