Question

what is isotones with example ? ​

Answer 1

Explanation:

Two nuclides are isotones if they have the same neutron number N, but different proton number Z. For example, boron-12 and carbon-13 nuclei both contain 7 neutrons, and so are isotones. Similarly, ³⁶S, ³⁷Cl, ³⁸Ar, ³⁹K, and ⁴⁰Ca nuclei are all isotones of 20 because they all contain 20 neutrons.

Answer 2

Answer:

Isotones are atomic species that share the same number of neutrons, and differ in the number of protons. Examples of isotones include carbon-12, nitrogen-13 and oxygen-14. ... Same Z (number of protons) = isotopes. Same A (number of nucleons) = isobars. Same N (number of neutrons) = isotones.
