Carbn dating

Some of those sugars are made into long chain molecules like cellulose, which makes up most of the woody, pulpy portion of trees and plants.Carbon dioxide gas also dissolves in water, sometimes forming carbonic acid.This process causes a proton to be displaced by a neutron, effectively turning atoms of Nitrogen it into an isotope of carbon – known as”radiocarbon”.It is naturally radioactive and unstable, and will therefore spontaneously decay back into N-14 over a period of time.
