The nuclei have been classified based on the number of protons (atomic number) or the total number of nucleons (mass number) as follows -
- Isotopes: The atoms of an element having the same atomic number but a different mass number are called isotopes. All isotopes have the same chemical properties.
- Isobars: The nuclei which have the same mass number (A) but a different atomic number (Z) are called isobars.
- Isotones: The nuclei having an equal number of neutrons are called isotones. For them both the atomic number (Z) and mass number (A) are different, but the value of (A – Z) is the same.
EXPLANATION:
- From above it is clear that the atoms of an element having the same atomic number but a different mass number are called isotopes. Therefore option 1 is correct.
- All isotopes have the same chemical properties.
