Therefore, the only thing we are changing is the atomic mass and the amount of neutrons present in each isotope.

In Carbon-12, there are 6 protons, 6 neutrons, and 6 electrons.

In Carbon-13, there are 6 protons, 7 neutrons, and 6 electrons.

In Carbon-14, there are 6 protons, 8 neutrons, and 6 electrons.
