Identify the element in question, which is carbon (C). Each element is defined by its atomic number.
Recall that the atomic number of an element represents the number of protons in one atom of that element.
Look up the atomic number of carbon on the periodic table, which is 6.
Understand that this means every carbon atom has 6 protons in its nucleus.
Therefore, the number of protons in one atom of carbon is equal to its atomic number, which is 6.
