1.	The highest electron affinity is shown by
Answer» `O^(-)` `F^(-)` `Cl_(2)` `F_(2)` Solution :The molecuels of `F_(2)` and `Cl_(2)` and the anion F, All have stable NOBLE gas CONFIGURATION. Therefore, their EA is ALMOST ZERO. However,`O^(-)` has one ELECTRON less than the noble gas configuration, therefore, `O^(-)` has the highest EA.
