Descrição
Boron is the fifth in the periodic table, it is also the only non-metallic element of the group 13 of the periodic table the elements and the smallest metalloid element.
Amorphous boron is a brown odorless powder, due to its boron atoms being bonded together in random order. It is different from crystalline boron is black in color and extremely hard.
