You are watching: Which of the following elements has the highest electronegativity


The correct answer is option 1, i.e. Fluorine.

Fluorine is the most electronegative element.As we move right in a period, the electronegativity keeps boosting up to the halogens.This is since the number of electrons keeps raising in the same valence covering so organize of the cell nucleus on the electron is tight.And as we move down in agroup, theelectronegativity decreases. This is as result of the truth that the number of shells keeps boosting down the team so the organize of the cell core on the valence electron(s) keeps decreasing.Since Flourine is the first member the the halogenfamily(the rightmost group prior to noble gases), as such it is the most electronegative element.
