Isotopes used for carbon dating

There are several ways to figure out relative ages, that is, if one thing is older than another.For example, looking at a series of layers in the side of a cliff, the younger layers will be on top of the older layers.In radioactive atoms the nucleus will spontaneously change into another type of nucleus.

But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes.You then subtract this amount from the total amount of daughter atoms in the rock to get the number of decays that have occurred since the rock solified.Here are the steps: a result of radioactive decay (call that isotope ``B'' for below).'' The age can still be determined but you have to be more clever in determining it.One common sense rule to remember is that the number of parent isotope atoms the number of daughter isotope atoms = an unchanging number throughout time.
