Question

Which of the following elements has the highest electronegativity?

• A. Oxygen
• B. Fluorine
• C. Chlorine
• D. Nitrogen

Hint:

Tip: Fluorine is the most electronegative element; it's used as a benchmark in Pauling’s scale.

Answer 1

The Correct Option is B

Electronegativity quantifies an atom's propensity to draw in and form bonds with electrons. Within the periodic table, electronegativity typically rises from left to right across a period and declines as one descends a group. Considering the provided elements:

• Oxygen (O): Ranks as the second most electronegative element, situated in group 16.
• Fluorine (F): Exhibits the highest electronegativity, positioned in group 17.
• Chlorine (Cl): Demonstrates lower electronegativity than fluorine, also located in group 17 but in the period directly below fluorine.
• Nitrogen (N): Possesses less electronegativity than oxygen, found in group 15.

Consequently, from the set of Oxygen, Fluorine, Chlorine, and Nitrogen, Fluorine exhibits the greatest electronegativity.
