But in graphite, each carbon atom bonds only to three others in a much looser arrangement of layers, each of which is weakly bonded to neighboring layers.Because individual layers of carbon in graphite are so loosely connected, they are easily scraped away, which is why it is used as pencil "lead" for writing. Symbol C An abundant nonmetallic element that occurs in many inorganic and in all organic compounds, exists freely in amorphous, graphite, and diamond forms and as a constituent of coal, limestone, and petroleum, and is capable of chemical self-bonding to form an enormous number of chemically, biologically, and commercially important molecules.Other significant allotropes include fullerenes and nanotubes.Ions can be created, by either chemical or physical means, via ionization. Oxygen is what makes the sky blue, molecules in the air scatter blue light from the sun more than they scatter red light.
