carbon dating is used to determine the age of biological artifacts up to 50000 years old this technique is widely used on recent artifacts but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old.
A further example from a lava flow off the coast of hawaii shows similar discrepancies if dated with the carbon14 method the flow appears to be less than 17000 years old but dating with the potassium argon method gives dates of 160000 to 43 million years.
carbon from latin carbo coal is a chemical element with symbol c and atomic number 6 it is nonmetallic and tetravalentmaking four electrons available to form covalent chemical bondsit belongs to group 14 of the periodic table three isotopes occur naturally 12 c and 13 c being stable while 14 c is a radionuclide decaying with a.
To develop the idea that carbon dating is based on gathering evidence in the present and extrapolating it to the past students will use a simple graph to extrapolate data to its starting point this lesson is the third in a threepart series about the nucleus isotopes and radioactive decay the.
radiocarbon dating uses carbon isotopes radiocarbon dating relies on the carbon isotopes carbon14 and carbon12 scientists are looking for the ratio of those two isotopes in a sample most.

How radiometric dating works in general radioactive elements decay gradually into other elements the original element is called the parent and the result of the decay process is called the daughter element.
carbon is an extraordinary element it occurs in more different forms than any other element in the periodic table the periodic table is a chart that shows how chemical elements are related to each other.
