All atoms of an element have the same number of protons. When an atom gives off radiation, it turns into a different kind of atom. Some atoms decay very quickly,..Some materials are radioactive. When an atom of a radioactive substance gives off radiation, it becomes a new type of atom. There are two..There is more nitrogen gas in the air than any other kind of gas.

For example, all hydrogen atoms have one proton, all carbon atoms have 6 protons, and all uranium..Carbon-14 is an isotope of the element carbon. Most carbon atoms also have 6 neutrons, giving them an atomic mass of 12 ( = 6 protons 6 neutrons). About 4/5ths of Earth's atmosphere is nitrogen gas!

Traditional radiocarbon dating is applied to organic remains between 500 and 50,000 years old and exploits the fact that trace amounts of radioactive carbon are found in the natural environment.

Carbon-14 dating (also called "radiocarbon dating") is used to determine the age of materials that contain carbon that was originally in living things.The amount of carbon-14 in the air has stayed the same for thousands of years.There is a small amount of radioactive carbon-14 in all living organisms because it enters the food chain.For some reason, which I have not yet figured out, at least one person per week has been asking me about the Carbon-14 Radiometric Dating Technique.They want to know if it is accurate or if it works at all.
