Which element has the highest electronegativity on the Pauling scale?
Answer and explanation
Correct answer: A. Fluorine
- Step 1: Electronegativity increases across a period and decreases down a group. Step 2. Fluorine (Group 17, Period 2) is the most electronegative element with a Pauling value of 3.98 (approx 4.0). Answer: Fluorine. Why not the others: Oxygen has the second highest value of 3.44; Chlorine has a Pauling value of 3.16; Nitrogen has a value of 3.04.
