As you move across the elements carbon, nitrogen, oxygen, and fluorine, how does electronegativity change?

1. It reduces progressively from carbon to fluorine.
2. It grows steadily from carbon to fluorine.
3. It stays the same throughout the series.
4. It drops from carbon to oxygen and then rises again.

Correct answer: It grows steadily from carbon to fluorine.

Solution

Electronegativity increases steadily from carbon to fluorine due to the increase in nuclear charge and decrease in atomic radius.
