Assuming that elec affinity varies linearly within the groups of the odic table, what would you predict for the ele affinity of gF?

[Hint: That periodic table gives the configuration of the outer-shell electrons only; to find the full configuration, you must add the configuration of the preceding closed-shell element. For example, for 12Mg, add the configuration of 10N..] 10.30 Use the periodic table inside the back cover to find the full configurations of the following atoms: iron, silver, iodine, polonium.
