Radiocarbon is not stable; over time radiocarbon atoms decay into nitrogen atoms.
Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.
This has caused many in the church to reevaluate the biblical creation account, specifically the meaning of the word “day” in Genesis 1.
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.
An “isotope” is any of several different forms of an element, each having different numbers of neutrons.
The ratio of radiocarbon to stable carbon atoms in the atmosphere has varied in the past.
This calibration step eliminates any concern about fluctuations in historic radiocarbon to stable carbon ratios or decay rates.Atoms are made up of much smaller particles called protons, neutrons, and electrons.Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.This tendency to decay, called radioactivity, is what gives radiocarbon the name radiocarbon.The atmosphere contains many stable carbon atoms and relatively few radiocarbon atoms.Part of the result of these collisions is the production of radiocarbon (C, pronounced "c fourteen"), carbon atoms which are chemically the same as stable carbon, but have two extra neutrons.
