Electron Affinity

Postby Maggie Doan 1I » Sun Nov 04, 2018 5:28 pm

Which has a higher electron affinity, chlorine (Cl) or Neon (Ne)?

I know that chlorine has the higher electron affinity but why?

The Noble gasses are nonreactive. Neon has a greater effective charge, but its octet is complete, so it won't pick up any electrons, where chlorine will in order to complete the octet.

Basically this; Chlorine is reactive due to its noncomplete (7/8 e-) valence shell, which pulls electrons in to complete the octet.
