Electronegativity of all the elements of periodic table is mentioned in the above image.
(Note: Electronegativity has no unit. A scale of electronegativity was designed by scientist Linus Pauling. This scale ranks the elements with respect to each other and this scale is known as the Pauling electronegativity scale.)
As per the pauling electronegativity values, the most electronegative element on the periodic table is Fluorine with electronegativity of 3.98.
And the least electronegative element on the periodic table is Francium with electronegativity of 0.7.
Few more periodic tables with electronegativity values are given below.
