At standard temperature and pressure, it resists all but the strongest oxidizers.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.Graphite is a good electrical conductor while diamond has a low electrical conductivity.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 can be oxidised by hot concentrated nitric acid at standard conditions to mellitic acid, C Carbon sublimes in a carbon arc, which has a temperature of about 5800 K (5,530 °C or 9,980 °F).

Carbon (from Latin: carbo "coal") is a chemical element with the symbol C and atomic number 6.
