It is impractical even for books and papers, so the C14 notation is most commonly used, and we will do the same on this website. But there are three different kinds of carbon, which differ in a way that all are still true carbon, but their atomic structure is different.

Two are called C12 and C13, carbon with an atomic weight of twelve or thirteen respectively - which are the normal and stable carbon - and the last one is C14, an isotope of carbon, which is subject to a very slow and harmless radioactive decay.
