Question
Distinguish between isotopes and isobars. Give one example for each of the species.
✓
Answer
| S. No. | Isotopes | Isobars |
| 1. | The nuclides having the same atomic number (Z). | The nuclides having the same atomic mass (A) but. |
| 2. | But different atomic masses (A) are called isotopes. Examples: $^1_1\text{H},\ ^2_1\text{H},\ ^3_1\text{H}$ | Different atomic numbers (Z) are called isobars. Examples: $^3_1\text{H},\ ^3_2\text{He}$ |
