    S2–, O2–
  • b)
    Cl, S2–
  • c)
    F, Na+
  • d)
    N3–, P3–
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
In which of the following pair, both the species are isoelectronic but...
F- and Na+ both have 10 electrons .Atomic no of F is 9 and for Na it is 11.so for F-, 9 proton is pulling 10 electrons and for Na+,11 proton is pulling 10 electrons . So attractive force is more for Na+ compared to F-. So radius of F- is more than Na+.

In which of the following pair, both the species are isoelectronic but...
There is a tricky formula for ion radius proportional e-/z ,in option C for F- no of electron =10 and z=9 so 10/9 and in Na+ =10/11, from this value F- is greater than Na+, and also isoelectronic, so simple
