Quizplus · Accepted Answer

The atomic symbol for the element is Cl, which has 17 protons. The superscript for ³⁵ does not affect the number of protons or neutrons, only electrons. The atomic mass of chlorine is 35.5, which means it has 18 neutrons. The superscript for ³⁵ tells us that there are 18 electrons, which matches the number of protons in Cl. Therefore, the correct choice is C: 17 protons, 18 neutrons, and 18 electrons.
