- Chlorine
- Fluorine
- Nitrogen
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Electronegativity is the tendency of an atom to attract a shared pair of electrons towards itself in a chemical bond.
Step 2: Meaning
On the Pauling scale, electronegativity generally increases across a period (left to right) and decreases down a group (top to bottom).
Step 3: Analysis
Nitrogen, Oxygen, and Fluorine are in the same period. Fluorine is the furthest to the right in this group. Chlorine is below Fluorine in the halogen group, meaning its electronegativity is lower than Fluorine's.
Step 4: Conclusion
Fluorine is the most electronegative element in the entire periodic table with a value of approximately 4.0. Final Answer: (C)
