Vedclass · Accepted Answer

$Ne$

Vedclass · Answer

(B) The electron gain enthalpy of noble gases is positive due to their stable electronic configuration $(ns^2 np^6)$.Among the given noble gases,$Ne$ has the highest electron gain enthalpy (most positive value).As we move down the group,the atomic size increases,and the effective nuclear charge experienced by the incoming electron decreases,making it progressively easier to add an electron compared to the smaller atoms,although the values remain positive.Therefore,$Ne$ has the highest electron gain enthalpy among the options.

Among the options,the element with the highest electron gain enthalpy is

The formation of the oxide ion $O^{2-}_{(g)}$ requires first an exothermic and then an endothermic step as shown below:
$O_{(g)} + e^{-} \to O^{-}_{(g)}; \Delta H = -142 \, kJ \, mol^{-1}$
$O^{-}_{(g)} + e^{-} \to O^{2-}_{(g)}; \Delta H = 844 \, kJ \, mol^{-1}$
