ASince they are in the same row, they have approximately the same EA and AR
BFluorine has greater EA and nitrogen has greater AR
CNitrogen has greater EA and AR
DFluorine has greater EA and AR
ENitrogen has greater EA, while fluorine has greater AR
✓ Correct answer: B. Fluorine has greater EA and nitrogen has greater ARFluorine has greater electron affinity (EA) and nitrogen has greater atomic radius (AR). EA generally increases across a period due to the greater nuclear charge attracting electrons more strongly, while AR decreases across a period due to the additional protons pulling electrons closer to the nucleus.
