Which of the following statements is wrong about isotopes?
Correct answer: D. They possess different positions in the periodic table
- A. They possess different mass numbers
- B. They possess different physical properties
- C. They possess the same chemical properties
- D. They possess different positions in the periodic table
Explanation
This statement is incorrect. Isotopes of the same element share the same position on the periodic table because they have the same number of protons, and the periodic table is organized based on atomic number (number of protons).Isotopes of an element have the same number of protons (which determines the element's identity) but different numbers of neutrons. The differences in mass number among isotopes arise due to the varying number of neutrons in their nuclei.

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.
