Question
What is an isotope?
Answer
An isotope is an atom of the same element that has the same number of protons but a different number of neutrons. This results in different mass numbers for the isotopes of that element.
Explanation
This answer is strong because it clearly defines isotopes in terms of protons and neutrons, which is essential for understanding their role in chemistry. The question tests the student's recall of the definition of isotopes.
Common mistake
Misunderstanding Isotopes
Students often think isotopes are different elements rather than different forms of the same element.
Remember that isotopes are variations of the same element, distinguished only by their neutron count.
