# What are ""^12C, and ""^14C?

You have 2 isotopes of carbon: ""^12C; and ""^14C. Each isotope has 6 protons in its nuclei (this is what makes a CARBON) isotope.
In the nuclei of ""^12C and ""^14C, there are respectively $6$ and $8$ neutrons, neutrally charged, massive nuclear particles (the combined mass of the protons and the neutrons gives the isotope number). (Note that I don't have to write ""_6C because the $C$ symbol specifies the atomic number, $Z = 6$).
