Fluor: 4,1 (Paulings scale)
Flourine
Fluorine is the most electronegative element on the periodic table. It has the highest electronegativity value of 3.98.
Electronegativity is highest in the top right corner of the periodic table, with fluorine being the most electronegative element. Electronegativity decreases as you move down and to the left on the periodic table.
Electronegativity is not found on the Periodic Table of the Elements.
The element in period 4 of the Periodic Table with the highest electronegativity is krypton (2.96). The period 4 element with the lowest electronegativity is potassium (0.82).
Fluorine
In the right corner of the periodic table.
Fluorine is more electronegative than chlorine. It has the highest electronegativity on the periodic table.
Electronegativity increases to the right of the table and up the table. So the most electronegative elements are at the top right, the least electronegative are at the bottom left. Fluorine is generally said to be the most electronegative element. This is not strictly true since both Helium and Neon are obviously more electronegative - however it is no good to say so since they are both massively inert. Whereas the electronegativity of Fluorine is important as it helps define its chemistry. Oxygen, nitrogen and chlorine all have high electronegativity but it tends to become a bit of a non-issue beyond that.
Chlorine. Chlorine is the highest on the periodic table and the most in the right direction. That is how electronegativity can be determined in these type lists. Across the periodic table from left to right and up into the right corner to go from lowest to highest electronegativity .
The highest element on the periodic table is Oganesson, with atomic number 118. It is a synthetic element that was first synthesized in 2002.
Yes chlorine does have highest electro-negativity due to its highest electron gain enthalpy
