Radio active dating who is jay kay dating
One of the interesting applications of radioactive decay is the technique of radioactive dating.
Radioactive dating allows the estimation of the age of any object which was alive once, using the natural radioactivity of .
It also allows the estimation of the age of geological samples using the decay of long lived nuclides.
All radioactive decays follow first order kinetics.
Each element comes in different forms, called isotopes, most of which are stable and do not change.
Some isotopes, however, are unstable and decay radioactively into other elements.
The sand grains at the top of the sealed glass are like the atoms of the parent isotope in the rock, and those at the bottom like the atoms of the daughter.The unstable potassium isotope is called the parent while the argon product is called the daughter.There are a couple of different radioactive forms of uranium that decay into lead.Radioactive decay occurs at a constant rate, specific to each radioactive isotope.Since the 1950s, geologists have used radioactive elements as natural "clocks" for determining numerical ages of certain types of rocks. "Forms" means the moment an igneous rock solidifies from magma, a sedimentary rock layer is deposited, or a rock heated by metamorphism cools off.
