Solution
Correct Answer:
Across a period from left to right
Electronegativity is the ability of an atom to attract shared electrons towards itself.
- Horizontal Trend: Increases from left to right across a period. This is due to the increase in effective nuclear charge and a decrease in atomic size, which increases the attraction for electrons.
- Vertical Trend: Decreases down a group. This is because the atomic size increases and the valence electrons are farther from the nucleus, weakening the attraction.
This easy difficulty chemistry question is from the chapter classification of elements and periodicity in properties, covering the topic of electronegativity. It appeared in the 2025 exam.
