Recall that the number of protons in an atom is equal to its atomic number, which uniquely identifies the element.
Identify the element given in the problem, which is carbon.
Look up the atomic number of carbon on the periodic table; this number represents the number of protons in a neutral carbon atom.
Understand that in a neutral atom, the number of protons equals the number of electrons, but the question only asks for protons.
Conclude that the number of protons in a neutral carbon atom is the atomic number of carbon.
