Explanation:

Step1: Relate carbon's protons to atomic number

Carbon has 6 protons, so its atomic number $Z=6$.

Step2: Find chlorine's atomic number

From periodic table, chlorine's atomic number $Z=17$.

Step3: Equalize electrons and protons (neutral atom)

Neutral atom: electrons = protons = 17.

Answer:

17
