There are about 2-3 relevant isotopes.

Explanation:

Most carbon chemistry is concerned with the 12C isotope. This is approx. 98.9% abundant. Of course, for carbon, Z=6, and this means that the nucleus contains 6 neutrons, 6 neutral, massive particles.

Approx. 1% of carbon atoms are the 13C isotope. The nucleus is amenable to 13C NMR spectroscopy, and as such is a very important means of characterization for organic chemistry.

There is a vanishingly small percentage of 14C, and this has a use in radiocarbon dating.

How many neutrons are present in the nuclei of each individual isotope?
