Question

How does the atomic radii trend explain the electronegativity trend?

Answer 1

From top to bottom down a group, electronegativity decreases. This is because atomic number increases down a group, and thus there is an increased distance between the valence electrons and nucleus, or a greater atomic radius.

Answer 2

Answer: electronegativity decreases.

Explanation: This is because atomic number increases down a group, and thus there is an increased distance between the valence electrons and nucleus, or a greater atomic radius.
