Question

Electronegativity increases across a period because:
Options
A Electron shielding increases
B Atomic number decreases
C Atomic size decreases and nuclear attraction increases
Correct Answer
D Electrons are added to inner shells
Correct Answer

Option C is the correct answer.

Detailed Explanation

Across a period, atomic radius decreases. This means the valence electrons are closer to the nucleus. The increasing nuclear charge and decreasing distance result in a stronger attraction between the nucleus and bonding electrons, increasing electronegativity.

Hint

A smaller atom with more protons can attract bonding electrons more effectively.
