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.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.Naturally occurring graphite occurs in two forms, alpha and beta.These two forms have identical physical properties but different crystal structures.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.

Before 1959, oxygen was the standard form used and it was in 1961 that Carbon 12 replaced oxygen as the standard form of measurement. On the other hand, Carbon 14 has 6 protons and eight neutrons. Carbon 12 is a stable isotope and Carbon 14 is an unstable isotope. As Carbon 14 is unstable, it disintegrates or goes through radioactive decay. Carbon 12 has its own importance as it is used as a standard form for measuring the atomic weight of all elements 6.

Carbon 12 vs Carbon 14 Carbon 12 and Carbon 14 are isotopes of Carbon. These two Carbon isotopes mainly differ in their mass number; the mass number of Carbon 12 is 12 and that of Carbon 14 is 14.
