1.

Statement 1: F atom has aless negative electron affinity than Cl atom statement 2: Additional electrons are repelled more effectively by 3p electrons in Cl atom than by electrons in F atoms

Answer»

Statement 1 is true, statement 2 is true, statement 2 si a correct EXPLANATION for statement 5
Statement 1 is true, statement 2 is true, statement 2 is not a correct explanation for statement 5
Statement 1 is true, statement 2 is false
Statement 1 is false, statement 2 is true

Solution :F has slightly LESS electron affinity than CHLORINE because F has verysmall atomic size (only TWO SHELLS). Hence results in less evolution of energy in the formation of `F^(-)` ion. Statement 1 correct but statement 2 incorrect.
