why do isotopes have different physical properties?
Correct answer: C. Isotopes of an element have different mass numbers, influencing their physical properties.
- A. Isotopes have the same electronic configuration because they have the same atomic number.
- B. Isotopes have the same atomic number, affecting their chemical properties.
- C. Isotopes of an element have different mass numbers, influencing their physical properties.
- D. Isotopes of an element have different atomic numbers.
Explanation
The variation of atomic mass in isotopes can influence its physical properties like Density, Melting and boiling point and stability.1)Higher atomic mass means high density2)Higher atomic mass means higher melting and boiling point.3)Higher or lower atomic mass also influences its density to be slightly high or low.

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.
