Carbon has by definition 6 protons. However, its many isotopes can have anywhere from 2 neutrons to 16 neutrons, with 6 neutrons being the most common (~95% of all carbon). Carbon has by definition <b>6 protons</b>.
Atoms of the same element can have differing numbers of neutrons. These differing versions of a given element are called isotopes. For example, carbon atoms have 6 protons in the nucleus, and therefore 6 electrons orbiting the nucleus, making the entire atom neutral. The number and energies of the electrons determine the chemical properties of carbon: its melting and boiling points, what other atoms it bonds with (or doesn't), etc.
