Arrange S, Cl and F in order of decreasing electron affinity. Cl > F > S F > Cl > S F > S > Cl Cl > S > F |

Answer» rect order of decreasing electron affinity is:Cl > F > S- The electron affinity becomes more negative UPON MOVING from left to right across a period. - So, chlorine has more electron affinity than sulphur.- The electron affinity becomes less negative upon moving from TOP to BOTTOM in a GROUP. - Chlorine should have a less electron affinity than chlorine but it is not the case.- In fact, fluorine has a less negative electron affinity than chlorine because of its small size and hence more repulsion.- So, the correct order becomes Cl > F > S. |
