Who discovered carbon dating
Naturally occurring graphite occurs in two forms, alpha and beta.These two forms have identical physical properties but different crystal structures.
Once an organism dies, it no longer ingests much of anything.
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.
In diamond, each carbon atom bonds to four others in a dense network that makes the material the hardest substance known.
But in graphite, each carbon atom bonds only to three others in a much looser arrangement of layers, each of which is weakly bonded to neighboring layers.
