Question

The correct order of electron gain enthalpy with -ve sign of the elements of oxygen family in the periodic table is

O > S > Se
S > O > Se
S > Se > O
Se > O > S​

Answer 1

Answer:

The correct order of electron gain enthalpy with negative sign of F, Cl, Br, and I is Cl>F>Br>I Actually halogens have maximum electron gain enthalpy in the corresponding periods and it becomes less negative down the group. However, the negative electron gain enthalpy of fluorine is less than that of chlorine.
