Boron has two naturally occurring and stable isotopes, 11B (80.1%) and ,10B, (19.9%). Although the term “boron” is commonly referenced, it ,does, not occur in nature in an elemental state. Boron combines with oxygen and other elements to form boric ,acid,, or inorganic salts called borates. Boric ,acid, is sometimes found in volcanic spring waters.
