Question

Why is fluorine the most electronegative element?
Options
A Small size and high nuclear charge
B High ionization energy and large atomic radius
C High nuclear charge and small atomic radius
Correct Answer
D Large shielding effect
Correct Answer

Option C is the correct answer.

Detailed Explanation

Fluorine has a very high nuclear charge (+9) but its valence electrons are in the second shell, very close to the nucleus. This combination of high nuclear charge and small atomic radius results in an extremely strong attraction for bonding electrons, making it the most electronegative element.

Hint

It's a combination of a strong pull from the nucleus and a very short distance to the bonding electrons.
