|||
|
(a) |
N3 −,Li+,Mg2+ and O2 − |
(b) |
Li+,Na+,O2 −and F − |
|
(c) |
N3+,O2 −,F − and Na+ |
(d) |
F − ,Li+ ,Na+ and Mg2+ |

(d) |
F − ,Li+ ,Na+ and Mg2+ |
Atomic numbers of N, O, F and Na are 7, 8, 9 and 11 respectively .Therefore, total number of electrons in each of N3−, O2−, F− and Na+ is 10 and hence they are isoelectronic.
