boron | Properties, Uses, & Facts | Britannica

Boiling hydrochloric acid does not affect it, and hot concentrated nitric acid only slowly converts finely powdered boron to boric acid (H 3 BO 3). Boron in its chemical behaviour is nonmetallic. In nature, boron consists of a mixture of two stable isotopes — boron-10 (19.9 percent) and boron-11 (80.1 percent); slight variations in this proportion produce a range of ±0.003 in the atomic
