The electronegativity of the following elements increases in the order
Correct answer: C. C: F > O > Cl > S
- A. A: F > Cl > O > S
- B. B: S > Cl > O > F
- C. C: F > O > Cl > S
- D. D: Cl > F > O > S
Explanation
The correct order of increasing electronegativity is F > O > Cl > S. Electronegativity increases across a period from left to right and decreases down a group. Therefore, among the given elements, fluorine has the highest electronegativity, followed by oxygen, then chlorine, and finally sulfur. Option A is incorrect because Cl should not come before O. Option B is incorrect because S and Cl are not more electronegative than O and F. Option D is incorrect because Cl should not come before F.

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.
