How to use carbon 14 dating

is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past. To understand radiocarbon dating, you first have to understand the word Although an element’s number of protons cannot change, the number of neutrons can vary slightly in each atom.

For example, age of the earth, moon, rocks, and mineral deposits can be determined by using the principle of radioisotopic dating.As you may know, most of the, if not all, objects that we see around us are made of carbon compounds.For example, plastic, stones, plants, animals and so on.They have the same ratio of carbon-14 to carbon-12 as the atmosphere, and this same ratio is then carried up the food chain all the way to apex predators, like sharks.But when gas exchange is stopped, be it in a particular part of the body like in deposits in bones and teeth, or when the entire organism dies, the ratio of carbon-14 to carbon-12 begins to decrease.
