Verified step by step guidance1
Recall that the number of protons in an atom is defined by its atomic number, which is unique for each element.
Identify the element in question, which is carbon in this problem.
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 a neutral atom has an equal number of protons and electrons, but the number of protons is fixed by the atomic number.
Conclude that the number of protons in a neutral carbon atom is equal to the atomic number of carbon.
