WebCorrect option is A) O 2− & F − are isoelectronic and O − and F are isoelectronic. For isoelectronic species, the element of the higher atomic number is smaller. Also for ions of the same element, more negative ions are bigger. Both trends are because of effective nuclear charge. Thus the conclusions are O 2−>O −;F −>F,O −>F,O 2−>F −. WebRadius of potassium ion = 138pm. Atoms and ions which consist of an equal number of electrons are considered isoelectronic species. For example, Both O 2-, Mg 2+ have 10 …
