Which of the following has highest electron affinity?
Correct answer: C. F
- A. NR+
- B. O
- C. F
- D. O-
Explanation
The correct answer is option C: F. Fluorine has the highest electron affinity among the elements listed. This is because fluorine is a highly electronegative element with a strong attraction for electrons, making it release the most energy when gaining an electron. Option A, B, and D are incorrect as they do not represent elements with the highest electron affinity.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
