The isoelectronic set of ions is : (1) F– , Li+ , Na+ and Mg2+ (2)

1.	The isoelectronic set of ions is : (1) F– , Li+ , Na+ and Mg2+ (2) Li+ , Na+ , O2– and F– (3) N3– , O2– , F– and Na+ (4) N3– , Li+ , Mg2+ and O2–
Answer» Correct option (3) N^3– , O^2– , F^– and Na⁺ Explanation: In this we have to choose isoelectronic set of ions Isoelectronic species are those which have same no. of electron in total. So option 3 : is correct.

The isoelectronic set of ions is : (1) F– , Li+ , Na+ and Mg2+ (2) Li+ , Na+ , O2– and F– (3) N3– , O2– , F– and Na+ (4) N3– , Li+ , Mg2+ and O2–

Answer»

Correct option (3) N^3– , O^2– , F^– and Na⁺

Explanation:

In this we have to choose isoelectronic set of ions

Isoelectronic species are those which have same no. of electron in total.

So option 3 : is correct.
