Question
The formation of the oxide ion 
requires first an exothermic and then an endothermic step as shown below
This is because
- (a)
ion will tend to resist the addition of another electron - Oxygen has high electron affinity
- (c) Oxygen is more electronegative
- ion has comparatively larger size than oxygen atom
ion will tend to resist the addition of another electron ion has comparatively larger size than oxygen atom The correct answer is: (a) ion will tend to resist the addition of another electron
The addition of second electron in an atom or ion is always endothermic.
