Understanding the Answer
Let's break down why this is correct
Answer
Among the first ten elements, fluorine is the most electronegative, meaning it pulls electrons toward itself the strongest. Electronegativity generally rises across a period, so the right‑most element in the first period (after hydrogen) shows the greatest pull. Fluorine’s electronegativity is about 4. 0 on the Pauling scale, higher than oxygen (3. 5) and nitrogen (3.
Detailed Explanation
Fluorine is the most electronegative of the first ten elements because it strongly pulls electrons toward itself. Other options are incorrect because Many think oxygen is the most electronegative, but it is less than fluorine; Nitrogen is often mistaken for very electronegative because it forms many bonds.
