Answer:
fluorine
Thus, fluorine is the most electronegative element, while francium is one of the least electronegative.
please mark me as brainlist answer
Explanation:
Fluorine is the most electronegative element on the periodic table. It has an electronegativity of 3.98 on the Pauling Electronegativity Scale.
Electronegativity increases along the periodic table from left to right, and from bottom to top, ignoring the unreactive noble gases. Fluorine is at the topmost, rightmost point.
Fluorine is the most electronegative element because:
It has 5 electrons in its 2p shell
The optimal electron configuration of the 2p orbital contains 6 electrons
Since fluorine is so close to ideal electron configuration, the electrons are held very tightly to the nucleus
A fluorine atom needs one electron to fill its outer electron shell and achieve stability, which is why free fluorine exists as the F- ion
