Correct Answer: Option C
Explanation
Chlorine (atomic number 17) exists as two naturally occurring stable isotopes:(75.77% natural abundance, mass ≈ 35) and(24.23% natural abundance, mass ≈ 37). The standard atomic weight is the weighted average:. This is NOT due to half-neutrons or half-protons (which do not exist) but is a statistical average across all naturally occurring chlorine atoms.
