Boron is a chemical element with symbol B and atomic number 5. [1]. It is a non-metallic element and the only non-metal of the group 13 of the periodic table. Boron is electron-deficient, possessing a vacant p-orbital. It has several forms, the most common of which is amorphous boron, a dark powder, unreactive to oxygen, water, acids and alkalis. It reacts with metals to form borides. At standard temperatures boron is a poor electrical conductor but is a good conductor at high temperatures. [2] Boron is found in the environment primarily combined with oxygen in compounds called borates. Common borate compounds include boric acid, sodium tetraborates (also referred to as borax) and boron oxide. [3]
