Carbon dating for idiots
Isotopes There are two stable naturally occurring isotopes of carbon, carbon-12 and carbon-13.Carbon-12 makes up almost 99% of the carbon found on Earth.
The starting ratio of radiocarbon to stable carbon is locked in at that point. The purpose in each of these methods is to determine the ratio of radiocarbon to stable carbon in the sample.Thus the ratio of radiocarbon to stable carbon in living animal tissue is also virtually the same as the ratio of radiocarbon to stable carbon in the atmosphere at any given time.This ratio is the same for all organisms across the globe at a given time due to the mixing of the atmosphere mentioned above.Diamonds are also used for their hardness in cutting tools and precision instruments. People have known about carbon as a substance since ancient times.French scientist Antoine Lavoisier determined that diamond was made of carbon in 1772. Carbon gets its name from the Latin word "carbo" meaning charcoal or coal.
Carbon is the fourth most abundant element in the universe by mass and the second most abundant element in the human body.
