Answer 1

Answer:

Isoelectronic species contain same number of electrons.

(i) Both F

−

and O

2−

contain 10 electrons each. Hence, they are isolectronic.

(ii) Both Ar and Cl

−

contains 18 electrons each. Hence, they are isoelectronic.

(iii) Both Mg

2+

and Na

+

contain 10 electrons each. Hence, they are isoelectronic.

(iv) Both Rb

+

and Kr contain 36 electrons. Hence, they are isoelectronic.
