Which one is true about isotopes?
Correct answer: D. Same chemical properties
- A. Same number of neutrons
- B. Same mass number
- C. Same physical properties
- D. Same chemical properties
Explanation
Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. Since isotopes have the same number of protons and electrons therefore, the chemical properties determined by the electrons are also the same.

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.
