What of a particular element have the same number of protons in their nucleus, but different numbers of neutrons. This means that although they are very how chemically, they have different masses. The total mass of the isotope is indicated by the numerical superscript. While the lighter isotopes 12 C and 13 C are stable, the heaviest isotope 14 C radiocarbon radiocarbon radioactive.

The isotope of carbon that is used for dating things in archeology?
Stable isotope analysis is a scientific technique which is used by archaeologists and other scholars to collect information from an animal's bones to identify the photosynthesis process of the plants it consumed during its lifetime. That information is enormously useful in a wide number of applications, from determining the dietary habits of ancient hominid ancestors to tracing the agricultural origins of seized cocaine and illegally poached rhinoceros horn. All of the earth and its atmosphere is made up of atoms of different elements, such as oxygen, carbon, and nitrogen. Each of these elements has several forms, based on their atomic weight the number of neutrons in each atom.
The ability to precisely date, or identify the age of an object, can teach us when Earth formed, help reveal past climates and tell us how early humans lived. So how do scientists do it? Radiocarbon dating is the most common method by far, according to experts. This method involves measuring quantities of carbon, a radioactive carbon isotope — or version of an atom with a different number of neutrons.
