- A. Same number of neutrons
- B. Same mass number
- C. Same physical properties
- D. All of these
Explanation
The correct answer is D) "All of these." Isotopes have different numbers of neutrons, different mass numbers, and while they have similar chemical properties, they can have slight variations in physical properties due to differences in atomic mass.

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.
