The nuclei having same number of neutrons but different number of protons are called- Correct Answer 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:

  1. 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.
  2. Isobars: The nuclei which have the same mass number (A) but a different atomic number (Z) are called isobars.
  3. 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:

  • The nuclei having the same number of neutrons but the different numbers of protons are called isotones.
  • Hence option 3 is correct.

It is related with the transformation of heavier nuclei into smaller nuclei. 3. It is related with the creation of a heavier nuclei by means of combining two higher nuclei. Select the correct answer using the code given below :
Seven people A, B, C, D, E, F and G live on separate floors of a 7-floor building. Ground floor is numbered 1, first floor is numbered. 2 and so on until the topmost floor is numbered 7. Each one of these having a different cars-Cadillac, Ambassador, Fiat, Maruti, Mercedes, Bedford and Fargo but not necessarily in the same order. Only three people live above the floor on which A lives. Only one person lives between A and the one having a car Cadillac. F lives immediately below the one having a car Bedford. The one having a car Bedford lives on an even-numbered floor. Only three people live between the ones having a car Cadillac and Maruti. E lives immediately above C. E is not having a car Maruti. Only two people live between B and the one having a car Fargo. The one having a car Fargo lives below the floor on which B lives. The one having a car Fiat does not live immediately above D or immediately below B. D does not live immediately above or immediately below A. G does not have a car Ambassador. Question : How many people live between the floors on which D and the one having a car Bedford ?
