For which of these elements would the electron affinity process shown be least favorable?
1. H + e− ! H−
2. Li + e− ! Li−
3. F + e− ! F−
4. O + e− ! O−
5. N + e− ! N−
My best guess would have been Li, but apparently the answer is N, which has almost zero electron affinity.
for value for those elements. (Drag the cursor to the element.)
