Answer» `A rarr 2, B rarr 4, C rarr 1, D rarr 3` A. `Li^(+)lt Al^(3+)lt Mg^(2+)lt K^(+)` The cation with the greater positive charge will have a smaller radius because of the greater attraction of the electrons to the nucleus. Anion with the greater negative charge will have the larger radius. Positive charge `prop (1)/("ionic radius")` Negative charge `prop` ionic radius B. Greater positive charge, increases ENC in case of isoelectronic species while for same group elements, ENC decreases down the group. C. `Cl gt F gt Br gt I` Electron affinity of Cl is highest in halogen family. D. `F gt Cl gt Br gt I` Electronegativity of fluorine (F) is higher than that of Cl, Br and I. |
