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: $^3_1\text{H},\ ^3_2\text{He}$
