18. The formation of the oxide ion, O-2 (g), from oxygen atom requires first an exothermic and then an endothermic step as shown below :

O(g)+e−⟶O−(g);ΔfH∘=−141kJmol−1${\text{O}}_{(\text{g})}^{}+{\text{e}}^{-}⟶\text{O}{-}_{(\text{g})}^{};{\mathrm{\Delta }}_{\text{f}}^{}{\text{H}}^{\circ }=-141\text{kJ}{\text{mol}}^{-1}$
O−(g)+e−⟶O2−(g);ΔfH∘=+780kJmol−1

Thus process of formation of O-2 in gas phase is unfavorable even thought O-2 is isoelectronic with

neon. It is due to the fact that,

(1) Oxygen is more electronegative
(2) Addition of electron in oxygen results in larger size of the ion
(3) Electron repulsion outweighs the stability gained by achieving noble gas configuration
(4) O- ion has comparatively smaller size than oxygen atom

solve previous year Classification Of Elements And Periodicity In Properties Class 11 MCQs (at least past 10 years). Give as much mock tests as possible and do proper analysis. The most important is, give enough time at least 3 hours to chemistry and biology each day. Because unlike physics, chemistry and biology will not at all betray you on the actual exam day.

 Solving previous year Classification Of Elements And Periodicity In Properties Class 11 MCQs is beneficial because sometimes questions are repeated, you can practice time management. But if you wish to score more than 150+ marks for it, you have to practice more Classification Of Elements And Periodicity In Properties Class 11 MCQ. 

You should focus on NCERT ( specially for inorganic), back exercise questions, intext questions, examples. Also while solving these previous year Classification Of Elements And Periodicity In Properties Class 11 MCQs you may make many mistakes just like I did but always analyze them, it helps a lot.
