Radiocarbon dating uses a radioactive isotope of the element

These techniques, unlike carbon dating, mostly use the relative concentrations of parent and daughter products in radioactive decay chains.For example, potassium-40 decays to argon-40; uranium-238 decays to lead-206 via other elements like radium; uranium-235 decays to lead-207; rubidium-87 decays to strontium-87; etc.C) dating usually want to know about the radiometric[1] dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years.

The rate of decay of N in 5,730 years (plus or minus 40 years).

This also has to be corrected for.[2] Second, the ratio of C in the atmosphere at that time to be estimated, and so partial calibration of the “clock” is possible.

Accordingly, carbon dating carefully applied to items from historical times can be useful.

So, we have a “clock” which starts ticking the moment something dies.

Obviously, this works only for things which were once living.

We will deal with carbon dating first and then with the other dating methods.
