Solution: Electron affinity corresponds to the energy released or absorbed in which process (for atom A)? 1. A → A + + 2 e – 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 –

Problem

Electron affinity corresponds to the energy released or absorbed in which process (for atom A)?

1. A → A + + 2 e

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
