Match List-I with List-II:
Choose the correct answer from the options given below:
| List-I | List-II | ||
|---|---|---|---|
| A | Atomic number (\( Z \)) | I | Total number of protons and neutrons |
| B | Mass number (\( A \)) | II | Number of protons in the nucleus |
| C | Isobars | III | Same mass number, different atomic numbers |
| D | Isotopes | IV | Same atomic number, different mass numbers |
Choose the correct answer from the options given below:
Correct answer · Option 2
A-(II), B-(I), C-(III), D-(IV)
Explanation
Atomic number is number of protons (II), mass number is total protons + neutrons (I), isobars have same \( A \) and different \( Z \) (III), isotopes have same \( Z \) and different \( A \) (IV).
