Chlorine (Cl) has a relative atomic mass of 35.5. This noninteger value is due to:
Correct answer: A. Isotopes
- A. Isotopes
- B. A half proton
- C. A half neutron
- D. A half electron
Explanation
The fractional atomic mass of chlorine is because it's a mixture of isotopes, primarily chlorine-35 and chlorine-37. The listed atomic mass of 35.5 amu is the weighted average of these isotopes based on their natural abundances.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
