Question

1. as you move from top to bottom within a group in the periodic table, what happens to the electronegativity of the elements? electronegativity remains the same electronegativity decreases electronegativity increases electronegativity becomes unpredictable

Explanation:

As you move from top to bottom within a group in the periodic table, the distance between the nucleus and the out - most electrons increases, and the shielding effect of inner - shell electrons also increases. This results in a decrease in the ability of the nucleus to attract bonding electrons, thus electronegativity decreases.

Answer:

Electronegativity decreases
