Question

The group having isoelectronic species is
(A) 02-, F-, Na+, Mg2+
(B) 0-, F-, Na, Mg+
(C) 02-, F-, Na, Mg2+
(D) 0-,P-, Na, Mg2+​

Answer 1

Answer:

A

Explanation:

all are having 10 electrons in option A

O gains 2 electrons O2- has 10 electrons

F gains 1 electron F2- has 10 electrons

Na loses 1 electron Na+ has 10 electrons

Mg loses 2 electrons Mg2+ has 10 electrons

therefore option A has isoelectronic species
