Question:
The element with highest electronegativity value after fluorine is
The element with highest electronegativity value after fluorine is
Show Hint
Electronegativity generally increases across a period and decreases down a group. Fluorine is the most electronegative element, followed by oxygen.
Updated On: Jun 24, 2026
- Nitrogen
- Oxygen
- Chlorine
- Bromine
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Recall the concept of electronegativity.
Electronegativity is the tendency of an atom to attract the shared pair of electrons towards itself in a chemical bond.
Fluorine has the highest electronegativity value in the periodic table: \[ \chi_F=4.0 \]
Step 2: Compare the electronegativity values of given elements.
Approximate electronegativity values are: \[ Oxygen \approx 3.5 \] \[ Chlorine \approx 3.0 \] \[ Nitrogen \approx 3.0 \] \[ Bromine \approx 2.8 \] Among these, oxygen has the highest electronegativity after fluorine.
Step 3: Final conclusion.
Therefore, the element with highest electronegativity after fluorine is \[ \boxed{\text{Oxygen}} \]
