Step-by-Step Solution
Step 1: Define isotopes and isobars
Isotopes: same atomic number, different mass numbers. Isobars: same mass number, different atomic numbers.Step 2: Analyze options
Option stating isotopes have same atomic numbers and different mass numbers is correct.Step 3: Explain incorrect options
Isotopes do not have different atomic numbers; isobars do not have same atomic numbers; isobars do not have same atomic and mass numbers.Final Answer:
Isotopes have same atomic numbers and different mass numbers → Option AQuick Check:
Isotopes = Same atomic number, different mass number ✅
Quick Trick: Isotopes differ in neutrons; isobars differ in protons.
