## Successive Electron Affinities of Oxygen

### Reactions:

1. \( O + e^- \rightarrow O^- \)  
   - Change in Energy (\(\Delta E\)) = \( EA_1 \)

2. \( O^- + e^- \rightarrow O^{2-} \)  
   - Change in Energy (\(\Delta E\)) = \( EA_2 \)

The successive electron affinities for the above reactions are denoted as \( EA_1 \) and \( EA_2 \).

### Question:
Which of the following statements is correct regarding \( EA_1 \) and \( EA_2 \) and the ions formed in the above reactions?

### Options:

- [ ] There is not enough information to answer this question.
- [ ] \( EA_2 \) is always exothermic.
- [ ] \( O^{2-} \) is paramagnetic.
- [ ] \( O^- \) is paramagnetic.
- [ ] \( EA_2 \) is always endothermic.
- [ ] \( EA_1 \) is always less than zero.
