How is effective nuclear charge related to the electron affinity of oxygen and fluorine?
(more than one answer is possible)
The fluorine has a larger effective nuclear charge than oxygen.
The electron affinity becomes more exothermic (negative) as the effective nuclear charge increases.
The electron affinity becomes more endothermic (positive) as the effective nuclear charge increases.
The fluorine has a less exothermic electron affinity than oxygen.
The fluorine has a more exothermic electron affinity than oxygen.

I’m impressed, I need to say. Actually rarely do I encounter a weblog that’s both educative and entertaining, and let me tell you, you could have hit the nail on the head. Your thought is excellent; the issue is one thing that not sufficient individuals are talking intelligently about. I’m very blissful that I stumbled across this in my seek for one thing regarding this.
