Carbon Facts
Carbon (C) is a non-metallic element found abundantly on Earth in all three of its forms. The physical characteristics of carbon are widely different in each of its several allotropic forms, the best known of which are amorphous, graphite, and diamond. This tetravalent element has an atomic number of six and six protons in the nucleus, but its tetravalent property means it has four electrons available to form covalent bonds.
Interesting Carbon Facts:
Carbon is the fourth most abundant element in the universe after hydrogen, helium, and oxygen.
The three forms of carbon found freely in nature are the amorphous, graphite, and diamond, and each form has vastly different properties.
Graphite is one of the softest known materials, while diamond is the hardest known material.
A fourth form, buckminsterfullerene, was only discovered a few years ago.
Carbon is one of the few elements whose existence has been known and used since ancient times.
It was named as an element by Antoine Lavoisier in 1789.
The Latin, English, French, German, Dutch, and Danish words for carbon all literally mean "coal substance."
All forms of carbon are solids under normal temperatures and pressure conditions.
Carbon is present in all known life forms.
It is the second most abundant element in humans (about 18% of mass) after oxygen.
Carbon is known to form around ten million different compounds.
It has the highest sublimation point of all elements at 3915 K (3642 °C, 6588 °F).
Carbon has two naturally occurring stale isotopes on Earth, one of which (carbon-12) accounts for 98% of the carbon found in nature.
There are fifteen known isotopes of carbon.
Thanks to the complicated loop of the carbon cycle, the amount of carbon on Earth is effectively constant.
Carbon is the basis for many organic compounds, inorganic compounds, and organometallic compounds.
Pure carbon has a very low level of toxicity and can be handled or ingested, but some of its compounds are lethal.
Carbon has an extremely varied list of uses for industry and daily living, but two major industries to rely on carbon are the petrochemical industry and steel industry.
Carbon in its diamond form is used by both the gem industry and for its industrial purposes.
