🤓 Based on our data, we think this question is relevant for Professor Scribner's class at UMICH.
Electron affinity corresponds to the energy released or absorbed in which process (for atom A)?
1. A → A+ +2e–
2. A + e– → A–
3. None of these
4. A 50 electron volt electron collides with A to give A + + 2e–
5. A → A+ + e–
