Electronegativity Chart of All Elements

Electronegativity chart of all elements is mentioned below.
(Note: Electronegativity has no unit. Linus Pauling was a scientist who designed a scale of electronegative that ranks the elements with respect to each other. And this scale is known as Pauling electronegativity scale.)
The Pauling electronegativity values of the element ranges from the most electronegative element (Fluorine having electronegativity = 3.98) to least electronegative element (Francium having electronegativity = 0.7)
