what is the overall trend in ionization energy (ie) down a group on the periodic table (group or column)? ionization energy decreases down a group ionization energy increases down a group
Answer
Answer:
Ionization energy DECREASES down a group
Brief Explanations:
As you move down a group, atomic size increases. Outer - electrons are farther from the nucleus and less tightly held, so less energy is needed to remove them, thus ionization energy decreases.
