Electron gain enthalpies of halogens are largely negative. Explain.

Give reasons for the following: Electron gain enthalpies of halogens are largely negative.

Electron gain enthalpies of noble gases are negative.

The electron gain enthalpy values of halogens become more negative in the order: F gt C l gt B rgt I Comment on the statement.

Explain: Electron gain enthalpy of chlorine is more negative than fluorine.

Statement-1: Second electron gain enthalpy of halogens is always positive. Statement-2: Fluorine has most negative electron gain enthalpy.
