, 0-(g)+ e- -t 02-(g) ;A ~ H @= + 780 kJmo1-'
Thus process of formation of 02-in gas phase is unfavourableeven though 02-is isoelectronic with neon. It is due to the fact that,
(1) electron repulsion outweighs the stability gained by achieving noble gas configuration.
(2) 0- ion has comparatively smaller size than oxygen atom.
(3) oxygen is more electronegative.
(4) addition of electron in oxygen results in larger size of the ion.
