Download Solution PDFThe correct answer is isotones.
CONCEPT:
- The nuclei have been classified based on the number of protons (atomic number) or the total number of nucleons (mass number) as follows:
Isotopes | Isobars | Isotones |
Isotherms |
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. | The nuclei which have the same mass number (A) but a different atomic number (Z) are called isobars. Isobars occupy different positions in the periodic table so all isobars have different chemical properties. | 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. |
Isotherms are lines on a weather map that connects points of equal temperature. |
EXPLANATION:
- From the above, it is clear that nuclei having the same number of neutrons but a different mass number are called isotones. Therefore option 3 is correct.
