The most electronegative element is Fluorine with a score of 4.0 (the highest possible.) Across from Fluorine we also have N and O with high electronegativities. Electronegativity is basically how much elements 'want' electrons. A simple way to think about it is that the closer an element is to Fluorine, the higher its electronegativity is. Fluorine (the most electronegative element) is assigned a value of 4.0, and values range down to caesium and francium which are the least electronegative at 0.7. What happens if two atoms of equal electronegativity bond together? Consider a bond between two atoms, A and B.

Which elements have the highest electronegativities on the periodic table?

1 Answer

There isn't really a whole row that is the largest.

Explanation:

Elements from the halogen group including F, Cl, Br have pretty high electronegativities. The most electronegative element is Fluorine with a score of 4.0 (the highest possible.)

Electronegative Elements Examples

Across from Fluorine we also have N and O with high electronegativities.

Electronegativity is basically how much elements 'want' electrons. A simple way to think about it is that the closer an element is to Fluorine, the higher its electronegativity is.
