By comparing how much carbon-14 there is in the dead organism with the amount in a living one, the age of the dead organism can be estimated.

The half-life of uranium-238 is 4500 million years.

Other significant allotropes include fullerenes and nanotubes.

Atomic number 6; atomic weight 12.011; sublimation point 3,825°C; triple point 4,489°C; specific gravity of amorphous carbon 1.8 to 2.1, of diamond 3.15 to 3.53, of graphite 1.9 to 2.3; valence 2, 3, 4. a nonmetallic element existing in the three crystalline forms: graphite, diamond, and buckminsterfullerene: occurring in carbon dioxide, coal, oil, and all organic compounds.

When an organism, eg a tree, dies it stops taking in carbon dioxide.

The amount of carbon-14 in the wood decreases with time as it decays into nitrogen with a half-life of about 5700 years.

If half of the uranium-238 has turned into lead-206 the rock will be 4500 million years old.

Symbol C An abundant nonmetallic element that occurs in many inorganic and in all organic compounds, exists freely in amorphous, graphite, and diamond forms and as a constituent of coal, limestone, and petroleum, and is capable of chemical self-bonding to form an enormous number of chemically, biologically, and commercially important molecules.

Thus radioactive dating relies purely on assumptions.a nonmetallic element found combined with other elements in all organic matter and in a pure state as diamond and graphite. Diamonds and graphite are pure forms, and carbon is a major part of coal, petroleum, and natural gas. The element carbon is also important, however, outside the chemistry of living things.Carbon can bond to itself and forms an enormous number of important molecules, many of which are essential for life. The two most familiar forms of carbon—diamond and graphite—differ greatly because of the arrangement of their atoms.The isotope carbon-12 has been adopted as the standard for atomic wt; carbon-14, a radioisotope with a half-life of 5700 years, is used in radiocarbon dating and as a tracer. gr.: (of diamond) 3.51 at 20°C; (of graphite) 2.26 at 20°C.Symbol: C; atomic no: 6; atomic wt: 12.011; valency: 2, 3, or 4; relative density: 1.8–2.1 (amorphous), 1.9–2.3 (graphite), 3.15–3.53 (diamond); sublimes at 3367±25°C; boiling pt: 4827°C 1. Symbol C A naturally abundant, nonmetallic element that occurs in all organic compounds and can be found in all living things. Proteins, sugars, fats, and even DNA all contain many carbon atoms.
