What are the properties of carbon 14?
The nucleus of carbon 14 contains 6 protons and 8 neutrons, as opposed to the 6 and 6 found in ordinary carbon 12. The imbalance makes carbon 14 a radioisotope with a half-life of 5,700 years, and an emitter of beta particles. This radioactive isotope of carbon is called radiocarbon.

How do you write carbon-14?
The nuclear notation of carbon-14 is 146C .
What are the 4 properties of carbon?
The atomic number is carbon is 6.
Can diamonds be carbon dated?
Diamonds are vastly older than any archeological relic, so carbon dating—which can only date items back to around 60,000 years ago—isn’t possible. These radioactive isotopes are like tiny, slow-ticking clocks captured in the fabric of a diamond crystal.
How reliable is radiocarbon dating?
To radiocarbon date an organic material, a scientist can measure the ratio of remaining Carbon-14 to the unchanged Carbon-12 to see how long it has been since the material’s source died. Advancing technology has allowed radiocarbon dating to become accurate to within just a few decades in many cases.
What are two physical properties of diamond?
Physical Properties of Diamond
- has a very high melting point (almost 4000°C). Very strong carbon-carbon covalent bonds have to be broken throughout the structure before melting occurs.
- is very hard.
- doesn’t conduct electricity.
- is insoluble in water and organic solvents.
