Why how carbon 14 dating done Best onr on one cam sex sites
Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.
The ratio of carbon-12 to carbon-14 at the moment of death is the same as every other living thing, but the carbon-14 decays and is not replaced.Hence, it is a good way of determining the age of certain archaeological artifacts of biological origin (could be bone, fiber, wood, plant remnants etc.) up to about 50,000 years old.If a fossil has say 25% of carbon-14 as compared to living sample than it is 11460 years old (as it has one-fourth carbon it is 5730*2=11460 years old).For example, all carbon atoms have 6 protons, all atoms of nitrogen have 7 protons, and all oxygen atoms have 8 protons.The number of neutrons in the nucleus can vary in any given type of atom.
Each sample type has specific problems associated with its use for dating purposes, including contamination and special environmental effects.
