A carbon atom contains 6 protons, 6

neutrons, and 6 electrons?

yes.

Explanation:

carbon contains 6 protons, 6 electrons as well as 6 neutrons

Every carbon atom has six protons, and the majority of carbon atoms have six neutrons. A carbon-12 atom has 6 protons (6P) and 6 neutrons (6N). But some types of carbon have more than six neutrons. We call forms of elements that have a different number of neutrons, isotopes.
