When was boron discovered?

Boron was discovered in 1808. French chemists Joseph-Louis Gay-Lussac and Louis-Jaques Thénard and English chemist Sir Humphry Davy independently isolated the element, and all three are credited with its discovery.

Boron was discovered by combining potassium and boric acid. Its name comes from the Persian word "Burah" and the Arabic word "Buraq," both of which mean 'borax." When heated, boron gives off a green color, making it a desirable element for pyrotechnics. The compound borax is a common ingredient in laundry detergents and antiseptics.

Boron has an atomic number of five, atomic weight of 10.811 and atomic symbol of B. In its standard state, it is a solid that is classified as a semi-metal.
