The nucleus is made of protons and neutrons, and the electrons surround the nucleus, as shown in the illustration below.
Because these isotopes are unstable, they undergo decay, and in the process can emit alpha, beta and gamma rays.
If we calculate the number of neutrons for each carbon isotope, we can see that they differ from each other.
For carbon-12, we have 6 neutrons; for carbon-13, we have 7 neutrons; and for carbon-14, we have 8 neutrons.
You may notice if we look at the atomic masses of elements in the periodic table that they are rarely ever whole numbers, just like for carbon where the atomic mass is 12.011.
This is because the atomic mass of carbon is based on the average atomic masses of its isotopes and the abundance of each isotope.
