*atomic #6*
(from latin “carbo” for “coal / charcoal”)

(it is ‘non-metallic’ + ‘tetra-valent’—making 4 electrons available to form ‘co-valent chemical bonds’)
(3 isotopes occur naturally, 12C and 13C being stable, while 14C is a radioactive isotope, decaying with a half-life of about 5,730 years)
(‘carbon’ is one of the few elements known since ‘antiquity’)
(‘carbon’ is the 15th most abundant element in the Earth’s crust, and the 4th most abundant element in the universe by mass after ‘hydrogen’, ‘helium’, and ‘oxygen’)
(carbon’s abundance, its unique diversity of organic compounds, and its unusual ability to form polymers at the temperatures commonly encountered on Earth enables this element to serve as a common element of all known life)
(it is the second most abundant element in the human body by mass (about 18.5%) after ‘oxygen’)
(the atoms of carbon can bond together in different ways, termed ‘allotropes’ of ‘carbon’)
(the best known are ‘graphite’, ‘diamond’, and ‘amorphous’ carbon)
(the physical properties of ‘carbon’ vary widely with the allotropic form)
(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)
(‘graphite’ is a good electrical conductor while ‘diamond’ has a low electrical conductivity)
(under normal conditions, ‘diamond’, ‘carbon nanotubes’, and ‘graphene’ have the highest thermal conductivities of all known materials)
(all carbon allotropes are solids under normal conditions, with ‘graphite’ being the most thermodynamically stable form)
(they are chemically resistant and require high temperature to react even with ‘oxygen’)
(the most common ‘oxidation state’ of ‘carbon’ in inorganic compounds is +4, while +2 is found in ‘carbon monoxide’ and ‘transition metal carbonyl complexes’)
(the largest sources of inorganic carbon are ‘limestones’, ‘dolomites’, and ‘carbon dioxide’, but significant quantities occur in organic deposits of ‘coal’, ‘peat’, ‘oil’, and ‘methane clathrates’)
(‘carbon’ forms a vast number of compounds, more than any other element, with almost 10 million compounds described to date, and yet that number is but a fraction of the number of theoretically possible compounds under standard conditions)
.
(for this reason, carbon has often been referred to as the “king of the elements”)
