Vedclass · Answer

(A) Isotones are nuclei that have the same number of neutrons $(N)$ but different atomic numbers $(Z)$.Neutron number is calculated as $N = A - Z$,where $A$ is the mass number and $Z$ is the atomic number.For option $A$: $_{34}Se^{74} \implies N = 74 - 34 = 40$ and $_{31}Ga^{71} \implies N = 71 - 31 = 40$.Since both nuclei have $40$ neutrons,they are isotones.For option $B$: $_{42}Mo^{92} \implies N = 92 - 42 = 50$ and $_{40}Zr^{92} \implies N = 92 - 40 = 52$. Not isotones.For option $C$: These are isotopes (same $Z$,different $A$).For option $D$: $_{20}Ca^{40} \implies N = 20$ and $_{16}S^{32} \implies N = 16$. Not isotones.Therefore,the correct option is $A$.

The nuclei of which one of the following pairs are isotones?
