Question

What is the trend for Electronegativity for Group 17 elements along the column or (top to botom)?​

Answer 1

Answer:

Electronegativity decreases.

Explanation:

As the radius of the atom increases down group 17 from top to bottom, and the valence shell electrons are increasingly shielded, the positively charged nucleus exerts less of an attractive force on the electrons so it has less ability to attract electrons towards itself, hence, electronegativity decreases from top to bottom.
