Identify the atomic number of each element, as it represents the number of protons in an atom. The atomic number is typically found on the periodic table.
For carbon (12C), the atomic number is 6, which means it has 6 protons.
For nitrogen (17N), the atomic number is 7, indicating it has 7 protons.
For oxygen (16O), the atomic number is 8, so it has 8 protons.
For boron (11B), the atomic number is 5, meaning it has 5 protons. Compare the atomic numbers to determine which element has the greatest number of protons.
