Chlorine has………..electron afffinity than fluorine.

Electron gain enthalphy is the amount of energy involved when an isolated gaseous atom accepts an electron to form a monovalent anion the value of the electron gain enthalpy of halogens are given below: F : -328 KJ mol^(-1) Cl - 349 KJ mol^(-1) Br : -325 KJ mol^(-1) I : -295 KJ mol^(-1)Chlorine has more negative electron gain enthalpy than fluorine. why ?

a) On moving down a group what happens to electron gain enthalpy? b) Why chlorine shows more negative electron gain enthalpy than fluorine?

Ionisation potential and electron affinity of fluorine are 17.42 and 3.45 eV respectively. Calculate the electronegativity of fluorine.

Assign reason for the following:- The negative Value of electron gain enthalpy of fluorine is less than that of CI.

Which of the following has least electron affinity?

Chlorine has the most negative electron gain enthalpy'. Justify the statement.

In the formation of sodium chloride-sodium donated one electron, chlorine accepts one electron write the valencies of each element?
