The physical properties of carbon vary widely with the allotropic form.

For example, graphite is opaque and black while diamond is highly transparent.

Carbon-14 is continuously generated in the upper atmosphere when stray neutrons bombard atmospheric nitrogen (which is what most of the atmosphere is).

The reason carbon dating works is that the fresh carbon-14 gets mixed in with the rest of the carbon in the atmosphere and, since it’s chemically identical to regular carbon, gets worked into whatever is presently absorbing atmospheric carbon.

They each rely on a couple of different (thoroughly verified) principles.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 ten million compounds described to date, The allotropes of carbon include graphite, one of the softest known substances, and diamond, the hardest naturally occurring substance.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.
