1.	Which one of the following arrangements represents the correct order of least negative to most negative electron gain enthalpy for C, Ca, Al, F and O? (a) Al < Ca < O < C < F (b)Al < O < C < Ca < F (c) C < F < O < Al < Ca (d) Ca < Al < C < O < F
Answer» The correct option is : (d) Ca < Al < C < O < F Explanation: Electron gain enthalpy becomes less negative from top to bottom in a group while it becomes more negative from left to right within a period.
