Why does Fluorine have a higher electronegativity than Carbon?

Fluorine has a higher electronegativity than carbon

Explanation:

Electronegativity trend

-As you go from left to right across the periodic table, the electronegativity increases.

-As you go from top to bottom, the electronegativity decreases.

-We know that both carbon and fluorine are in the same energy level or period 2. However, Carbon is in group 14, which has 4 valence electrons, while fluorine is in group 17, which has 7 valence electrons. Therefore, fluorine has a higher electronegativity because fluorine is desperately wanted to gain 1 more valence electron to become stable (octet rule).
