Question

Explain why halogens possess highest electronegativity

Answer 1

Yes, they are attracted, but the farther and farther away from the nucleus youget, the less that attraction is. So, as you move down a group on the periodic table, the electronegativity decreases, and atoms have a moredifficult time attracting electrons.

Answer 2

Explanation:

1. An atoms electronegativity is affectes by both its atomic number and the distance at which its valence electronegativity reside from the charges nucleus.This reactivity is due to high electronegativity and high effective nuclear charge.Halogens can gain an electron by reacting with atoms of other elements. Fluorine is one of the most reactive elements.
