Following are the values of the electron gain enthalpy (in $\mathrm{kJ} {\mathrm{mol}}^{-1}$) of the formation of ${\mathrm{O}}^{-}$ and ${\mathrm{O}}^{2-}$ from $\mathrm{O}$:

Electron addition would be easier in:

The high oxidising power of fluorine is due to

Fluorine is more electronegative than nitrogen. The best explanation is that

Metallic nature increases moving down the group because

Select the correct statement.

Match List-$\mathrm{I}$ with List-$\mathrm{II}$ and then select the correct answer from the codes given below the lists:

Consider the following statements.

${\mathrm{S}}_1 :$ Fluorine does not form any polyhalide as it has low $\mathrm{F}-\mathrm{F}$ bond energy.

${\mathrm{S}}_2 :$ The chlorine has the most negative electron gain enthalpy.

${\mathrm{S}}_3 :$ The first ionization potential of $\mathrm{N}$ and $\mathrm{O}$ atoms are $14.6$ and $13.6 \mathrm{eV}$ respectively.

Which of the above statements are correct?
