Radiometric dating and carbon dating of fossils
The basic principle Carbon has three naturally occurring (n is a neutron and p is a proton) After formation the three carbon isotopes combine with oxygen to form carbon dioxide.The carbon dioxide mixes throughout the atmosphere, dissolves in the oceans, and via C in the original sample will have decayed and after another 5568 years, half of that remaining material will have decayed, and so on.This method should also be applied only to minerals that remained in a closed system with no loss or gain of the parent or daughter isotope.
Perseverance over three years of secret research to develop the radiocarbon method came into fruition and in 1960 Libby received the Nobel Prize for chemistry for turning his vision into an invaluable tool.The original atom is referred to as the parent and the following decay products are referred to as the daughter.For example: after the it forms a component of all organic compounds and is therefore fundamental to life. Libby of the University of Chicago predicted the existence of carbon-14 before it was actually detected and formulated a hypothesis that radiocarbon might exist in living matter.By determining the number of tracks present on a polished surface of a grain and the amount of uranium present in the grain, it is possible to calculate how long it took to produce the number of tracks preserved.As long as the mineral has remained cool, near the earth surface, the tracks will accumulate.
Shortly after Becquerel's find, Marie Curie, a French chemist, isolated another highly radioactive element, .
