Question

Highest electronegative element in periodic table

Answer 1

$\huge\underline\mathfrak\purple{Answer}$

fluorine

Answer 2

Answer:

Thus, fluorine is the most electronegative element, while francium is one of the least electronegative. (Helium, neon, and argon are not listed in the Pauling electronegativity scale, although in the Allred-Rochow scale, helium has the highest electronegativity.)

Explanation:

Of the main group elements, fluorine has the highest electronegativity (EN = 4.0) and cesium the lowest (EN = 0.79).F for fluorine, O for oxygen, N for nitrogen. Those are the 3 most electronegative elements. Chlorine is very close behind nitrogen, perhaps they are tied. Then comes bromine, iodine, followed by sulfur, carbon, hydrogen, and phosphorus.
