The black non-metal you are referring to is carbon. It has three well-known allotropes: diamond, which has a crystalline structure and is extremely hard; graphite, which consists of layers of carbon atoms and is used in pencils and lubricants; and charcoal, a porous form of carbon made from the incomplete combustion of organic materials. Each allotrope exhibits distinct physical properties and uses, despite being composed of the same element.
