Solution
Correct Answer:
Fluorine
Electronegativity is the tendency of an atom to attract a shared pair of electrons.
- Fluorine (F) is the most electronegative element in the periodic table (4.0 on the Pauling scale).
- This is due to its extremely small atomic radius and high effective nuclear charge (Zeff).
- Order: F(4.0)>O(3.5)>N(3.0)≈Cl(3.0).
This easy difficulty chemistry question is from the chapter chemical bonding and molecular structure, covering the topic of electronegativity. It appeared in the 2025 exam.
