"coal") is a chemical element with symbol C and atomic number 6.
It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.
Carbon is the sixth element, with a ground-state electron configuration of 1s, of which the four outer electrons are valence electrons.
Carbon is known to form almost ten million different compounds, a large majority of all chemical compounds.
Graphite is much more reactive than diamond at standard conditions, despite being more thermodynamically stable, as its delocalised pi system is much more vulnerable to attack.
For example, graphite is opaque and black while diamond is highly transparent.
Graphite is soft enough to form a streak on paper (hence its name, from the Greek verb "γράφειν" which means "to write"), while diamond is the hardest naturally occurring material known.
