Crystalline boron is a non-metallic element that exists in a few different forms, including a hard black powder and a dark, lustrous solid. It has a complex structure made up of interlocking B12 icosahedra which gives it its unique properties.
It is a network solid, a lattice of many covalent bonds (like diamond, except that it is black rather than transparent).
Boron has a rombohedral crystalline structure.
Crystalline boron is a type of covalent solid, characterized by a network of strong covalent bonds between boron atoms. This structure results in high hardness and high melting points, making it a durable material. Additionally, crystalline boron exhibits semiconductor properties, which can be useful in various electronic applications. Its unique bonding and structure contribute to its distinct physical and chemical properties.
At room temperature and standard pressure the element Boron is a solid.
The color of crystalline boron is black.
Crystalline/solid boron does not react at all with sulfuric acid. However, finely powered boron will react with sulfuric acid but very slowly.
