Comparison of electron affinity of Nitrogen and Carbon

[hojae_lee_1C]

According to the periodic trend, Nitrogen should have a higher electron affinity than Carbon. But once you check the electron affinities of each atom, Carbon's electron affinity is higher than that of Nitrogen. Does this have to do with the unpaired valence electrons in Carbon and the one paired valence electrons in Nitrogen? Can someone explain?

Nitrogen is more stable than carbon, so carbon has a greater electron affinity

[Katie 1E]

The reason that nitrogen is more stable than carbon because it has one electron in px, one in py, and one in pz. Carbon has an empty pz, so it has a higher electron affinity because it needs one more electron in the p subshell to make it more stable.
