Question
Explain why isotopes of the same element have the same chemical properties.
Answer
Isotopes of the same element have the same number of protons, which determines the element's identity and its chemical properties. Since chemical reactions involve the arrangement of electrons, and the number of electrons is equal to the number of protons in a neutral atom, isotopes will behave similarly in chemical reactions.
Explanation
This question tests the understanding of isotopes and their relationship to chemical properties. It assesses the student's ability to connect atomic structure with chemical behavior, reinforcing the concept that chemical properties are determined by electron configuration, which is identical in isotopes.
Common mistake
Misconception about chemical properties of isotopes
Students often think that isotopes of the same element have different chemical properties because they contain different numbers of neutrons.
Explain that chemical properties are determined by the arrangement of electrons, which is the same for all isotopes of an element. Neutrons only affect the mass and nuclear stability, not the electron configuration or chemical behaviour.
