Question
Why does electron affinity tend to become more exothermic as you move right across a period?
Hints
The trend in electron affinity is just the opposite of that for first ionization energy, since the two processes are the opposite of each other.
As you move right across the period, you have a greater likelihood of pairing electrons in an orbital, which is a more stable configuration.
ion is more likely to gain electrons than lose electrons.
attraction for an electron.
As you move right across the period, metallic character decreases, meaning that the atom or
The effective nuclear charge increases as you move right across the period, resulting in greater
