F^1-has small size than O^2-.
Explanation:
F^1-has small size because both have same electron(genraly O has 8electrons and F has 9 electrons they accepts 2and 1 electron respectively)
but they have different-diffrent nuclear charge F has more nuclear charge, so attraction between the electons and nucleus increses.so,F^1- has small size thenO^2-.
Hope this will help you.
