Question

Consider elements in group 17 of the periodic as you move from top to bottom the ionization energy of each element decreases why

Answer 1

Answer:

Conversely, as one progresses down a group on the periodic table, the ionization energy will likely decrease since the valence electrons are farther away from the nucleus and experience greater shielding. They experience a weaker attraction to the positive charge of the nucleus.
