Question

Why fluorine has less electronegativity han chlorine?

Answer 1

Hey Mate..

Fluorine is more electronegative that chlorine..

Fluorine is the most electronegative element because it has 5 electrons in its 2P shell. ... Flourine is smaller in size than chlorine . So it have large attractive forces between nucleus & outer most shell. So it is more electronegative.

Hope it helped ❤️❤️

Answer 2

In fact, fluorine is the most electronegative element in the periodic table. It is much smaller in size than chlorine and has a greater tendency to attract electrons than chlorine. However, the electron gain enthalpy of chlorine is more negative than fluorine. This is because fluorine is smaller in size than chlorine.
