Recall that the number of protons in a neutral atom is equal to its atomic number.
Identify the element in question, which is carbon.
Look up the atomic number of carbon on the periodic table; this number represents the number of protons.
Understand that the atomic number of carbon is 6, meaning it has 6 protons.
Confirm that since the atom is neutral, the number of protons equals the number of electrons, but the question only asks for protons.
