At room temperature, the chemical properties of elemental carbon are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents; it reacts with oxygen at different temperatures to produce carbon dioxide or carbon monoxide; only fluorine can react directly with elemental carbon in halogen; under heating, elemental carbon is more easily oxidized by acid; at high temperature, carbon can also react with many other substances. Metals react to form metal carbides. Carbon is reducible and can be smelted at high temperatures.
Graphite is a crystalline mineral of carbonaceous elements. Its crystal lattice is hexagonal layered structure. The distance between each network layer is 340pm, and the spacing of carbon atoms in the same network layer is 142pm. It belongs to six square crystal system with complete lamellar cleavage. The cleavage surface is mainly composed of molecular bonds, and its attraction to molecules is weak, so its natural floatability is very good.
Graphite, diamond, carbon 60 and carbon nanotubes are the elements of carbon, and they are allotropic to each other.
