Understand that the atomic number of an element is the number of protons in the nucleus of an atom of that element.
Recall that chlorine is represented by the symbol 'Cl' on the periodic table.
Look up chlorine on the periodic table or in the provided figure to find its atomic number, which is usually displayed above the element symbol.
Identify the atomic number associated with chlorine; this number is unique to chlorine and defines its position in the periodic table.
Confirm that the atomic number corresponds to 17, which means chlorine has 17 protons.
