However, scientists can look at the decay of other elements in these objects allowing them to date them up to 2.2 billion years. The alkali metals are the elements that make up Group 1 (IA) of the periodic table.Certain naturally occurring radioactive isotopes are unstable: Their nucleus breaks apart, undergoing nuclear decay.Sometimes the product of that nuclear decay is unstable itself and undergoes nuclear decay, too.The carbon in their bodies at the time of their death will remain in their bodies until they decompose, or if they become fossilized, then forever. This allows scientists to look at the amount of decay in a fossil’s radioactive carbon and determine a relative date.Radiocarbon dating is only effective for objects and fossils that are less than 50,000 years old.Ramzi Amri Your entire body is made of a lot cells, which are made of a lot of organic molecules, the framework of each of which is made of a lot of carbon.A carbon atom (generally speaking) is found to possess either 12 particles in its nucleus, or 14.

You may also witness chronic symptoms if you eat 274 bananas a day for seven years.The reason is that energy and frequency of a gamma ray which is emitted by a radioactive element, is far beyond that of the radio band of electromagnetic spectrum! Every nucleus contains neutrons as well as protons.Neutrons are neither positively charged, nor negatively charged, they are neutral particles. As you might remember from high school physics, like charges repel each other while unlike charges attract each other.For example, when U-238 (one of the radioactive isotopes of uranium) initially decays, it produces Th-234, which decays to Pa-234.The decay continues until, finally, after a total of 14 steps, Pb-206 is produced.Carbon combines with other elements in complex ways to form the molecules that make up our bodies.
