At high geomagnetic latitudes, the carbon-14 spreads evenly throughout the atmosphere and reacts with oxygen to form carbon dioxide.Carbon dioxide also permeates the oceans, dissolving in the water. If you have looked at a periodic table, you may have noticed that the atomic mass of an element is rarely an even number. If you are an atom with an extra electron, it's no big deal. As you learn more about chemistry, you will probably hear about carbon-14. C-14 is considered an isotope of the element carbon.Anthropologists, archeologists, and paleontologists also use radioactive isotopes to date mummies, pottery, and dinosaur fossils. It is no more complicated than playing a dice game! Roll the Dice & Use Radiometric Dating to Find Out.In this science project you will see for yourself by modeling radioisotope dating with a few rolls of the dice. Retrieved July 3, 2017 from https:// As humans, it seems easy for us to keep track of time lapses, as long as they range from a couple of seconds to a number of years.

When you average out all of the masses, you get a number that is a little bit higher than 12 (the weight of a C-12 atom).The amount of carbon-14 gradually decreases through radioactive beta decay with a half-life of 5,730 years.So, scientists can estimate the age of the fossil by looking at the level of decay in its radioactive carbon.However, it is also used to determine ages of rocks, plants, trees, etc. When the sun’s rays reach them, a few of these particles turn into carbon 14 (a radioactive carbon).

The highest rate of carbon-14 production takes place at altitudes of 9 to 15 km (30,000 to 50,000 ft).

In older stars that have burned most of their hydrogen, leftover helium accumulates.
