ስለ Boron
Boron is a metalloid that exists in many polymorphs, with the most common being amorphous brown powder and black crystalline forms. It is an essential micronutrient for plants but toxic in excess. Boron compounds have been known for thousands of years. Pure boron was first produced in 1808.
