Therefore, both have very high melting points. The melting point of graphite is slightly higher than the melting point of diamond because in graphite C___C bonds have partial double bond character and hence are stronger and difficult to break. In factor, carbon as graphite has the highest melting point among all the elements. 5.

Carbon (from Latin: carbo "coal") is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical belongs to group 14 of the periodic table. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide, decaying with a halflife of about 5,730 years.
Graphite has a high melting point, similar to that of diamond. In order to melt graphite, it isn''t enough to loosen one sheet from another. You have to break the covalent bonding throughout the whole structure. It has a soft, slippery feel, and is used in pencils and as a dry lubricant for things like locks. You can think of graphite rather ...

Graphite From Coal Seam Metamorphism ("Amorphous" Graphite) Some graphite forms from the metamorphism of coal seams. The organic material in coal is composed mainly of carbon, oxygen, hydrogen, nitrogen, and sulfur. The heat of metamorphism destroys the organic molecules of coal, volatilizing the oxygen, hydrogen, nitrogen, and sulfur.
